We are going to re-use tb_drom_read() for USB4 DROM reading as well. USB4 has separate router operations for this which does not need the drom_offset. Therefore we move call to tb_eeprom_get_drom_offset() into tb_eeprom_read_n() where it is needed. While there change return -ENOSYS to -ENODEV because the former is only supposed to be used with system calls (invalid syscall nr).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
