Subject: [PATCH] mmc: sdricoh_cs: remove redundant check if len is non-zero

From: Colin Ian King <colin.king@...onical.com>

At the end of either of the read or write loops len is always zero
and hence the non-zero check on len and return of -EIO is redundant
and can be removed.

Detected by CoverityScan, CID#114293 ("Logically dead code")
