From: Pavel Skripkin <paskripkin@xxxxxxxxx>
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.
