mmc: sdhci: host: fix odd_ptr_err.cocci warnings

drivers/mmc/host/sdhci_f_sdh30.c:143:5-11: inconsistent IS_ERR and PTR_ERR, PTR_ERR on line 144

 PTR_ERR should access the value just tested by IS_ERR

Semantic patch information:
 There can be false positives in the patch case, where it is the call
 IS_ERR that is wrong.
