rsi: Fix 'invalid vdd' warning in mmc

BugLink: https://bugs.launchpad.net/bugs/1791953

[ Upstream commit 78e45071 ]

While performing cleanup, driver is messing with card->ocr
value by not masking rocr against ocr_avail. Below panic
is observed with some of the SDIO host controllers due to
this. Issue is resolved by reverting incorrect modifications
to vdd.
