mtd: rawnand: qcom: Handle unsupported opcode in qcom_op_cmd_mapping()

Browse source

Handle the scenario where the caller has passed an unsupported opcode to
qcom_op_cmd_mapping(). In that case, log the error and return the
-EOPNOTSUPP errono. Also, let's propagate this error code all the way up.

This also fixes the following smatch warning:

drivers/mtd/nand/raw/qcom_nandc.c:2941 qcom_op_cmd_mapping() error: uninitialized symbol 'ret'.
