urtwn(4): rework ROM reading.

- Add error handling for urtwn_(r88e_)read_rom() and
urtwn_efuse_*() functions.
- Remove code duplication between urtwn_efuse_read() and
urtwn_r88e_read_rom().
- Merge r88e_rom and (r92c_)rom structures
(only one of them can be used at the same time).
- Other minor fixes / improvements.

Tested with RTL8188EU, STA mode
(URTWN_DEBUG + USB_DEBUG, hw.usb.urtwn.debug=3, no visual differences).
