[PATCH v7 09/19] staging: r8188eu: remove the helpers of usb_read_port()

From: Pavel Skripkin <paskripkin@gmail.com>

Remove the unnecessary _rtw_read_port() and usb_read_port() and embed their
code into the caller (i.e., rtw_read_port()).

_rtw_read_port() is a mere redefinition of rtw_read_port() and it is
unneeded. usb_read_port() was the only functions assigned to the
(*_usb_read_port) pointer, so we can simply remove it and make a direct
call.

This patch is in preparation for the _io_ops structure removal.
