Colin Ian King 9ccb645683 altera-stapl: check for a null key before strcasecmp'ing it
Currently the null check on key is occurring after the strcasecmp on
the key, hence there is a potential null pointer dereference on key.
Fix this by checking if key is null first. Also replace the == 0
check on strcasecmp with just the ! operator.

Detected by CoverityScan, CID#1248787 ("Dereference before null check")

Fixes: fa766c9be5 ("[media] Altera FPGA firmware download module")
