mmc: sdhci-of-arasan: Check return value of non-void funtions
[ Upstream commit 66bad6ed2204fdb78a0a8fb89d824397106a5471 ]
At a couple of places, the return values of the non-void functions were
not getting checked. This was reported by the coverity tool. Modify the
code to check the return values of the same.
Addresses-Coverity: ("check_return")
