[PATCH v5 02/19] staging: r8188eu: remove the helpers of rtw_read8()

Fabio M. De Francesco

Remove the unnecessary _rtw_read8() and usb_read8() and embed their
code into the caller (i.e., rtw_read8()).

_rtw_read8() is a mere redefinition of rtw_read8() and it is unneeded.
usb_read8() was the only functions assigned to (*_usb_read8) pointer,
so we can simply remove it and make a direct call.

This patch is in preparation for the _io_ops structure removal.
