Remove function rtw_init_mlme_priv() as all it does is call
_rtw_init_mlme_priv().
Change the name of _rtw_init_mlme_priv() to rtw_init_mlme_priv() and its
return type to int.
Remove references to _rtw_init_mlme_priv() from the corresponding header
file.
Suggestion to delete return variable from rtw_init_mlme_priv() put forward
by Coccinelle using ret.cocci.

The buffer descriptor setup loop is correct only if it is setting up at
least one bd struct. Besides, there is an error if dma_map_sg() returns
0, which is possible and must be handled.
Additionally, remove the BUG_ON() checking sglen, which is unnecessary
because we configure DMA with that constraint during init.

rtw_startbss_cmd can return the result of calling rtw_enqueue_cmd, which
can return the result of calling _rtw_enqueue_cmd, but they all have
different return types (u8, u32, and sint, respectively).
As all of these functions return error codes, change all the return types
to int, in preparation for converting these functions to use standard
kernel error codes.
Also, remove extern from the function declaration to maintain Linux kernel
coding style.

The `insn_read` handler for the EEPROM subdevice on M-series boards
(`ni_m_series_eeprom_insn_read()`) currently ignores `insn->n` (the
number of samples to read) and assumes a single sample is to be read
into `data[0]`. Fortunately, the Comedi core ensures that `data[]` has
a length of at least 16 so there is no problem with array bounds.
The usual Comedi convention for `insn_read` handlers is to read the same
channel `insn->n` times into successive elements of `data[]` so let's do
that. (Each channel corresponds to a single EEPROM address.) In this
case, the data value comes from a local copy of the EEPROM contents.
Also, follow the usual Comedi convention and return `insn->n` from the
handler to indicate success (although any non-negative value will do).
