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 ||?

Reported-by: kernel test robot <lkp@intel.com>
Reported-by: Dan Carpenter <dan.carpenter@linaro.org>
Closes: https://lore.kernel.org/r/202308032022.SnXkKyFs-lkp@intel.com/
Fixes: 89550beb098e ("mtd: rawnand: qcom: Implement exec_op()")

Applied to https://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux.git nand/next, thanks.
