staging: rts5208: fix missing error check on call to rtsx_write_register

[ Upstream commit c5fae4f4fd28189b1062fb8ef7b21fec37cb8b17 ]

Currently the check on error return from the call to rtsx_write_register
is checking the error status from the previous call. Fix this by adding
in the missing assignment of retval.
