[PATCH 04/10] mtd: rawnand: qcom: Fix the opcode check in qcom_check_op()

[Manivannan Sadhasivam]

qcom_check_op() function checks for the invalid opcode for the instruction
types. Currently, it just returns -ENOTSUPP for all opcodes of
NAND_OP_CMD_INSTR type due to the use of "||" operator instead of "&&".
Fix it!

This also fixes the following smatch warning:

drivers/mtd/nand/raw/qcom_nandc.c:3036 qcom_check_op() warn: was && intended here instead of ||?
