rust: error: add remaining error codes

Browse Source 
Add all of the remaining error codes from include/uapi/asm-generic/errno.h.

Previous updates to error.rs have been piecemeal -- adding single error
codes as needed.  Instead, we can avoid future problems by adding all
the remaining error code in one swoop.

EDEADLOCK and EWOULDBLOCK are intentionally left out: they are just
deprecated compatibility aliases of EDEADLK and EAGAIN, kept around for
non-Linux/POSIX code, and have no use in new kernel code.
