LF-3626: mtd: nand: gpmi: fix the explicit null dereference issue

A potiential null pointer dereference issue may occur in
gpmi_nfc_exec_op(), found by coverity, CID 9000785.

In the for loop, if loop continues in NAND_OP_CMD_INSTR case, the desc
pointer may leave as null, so move the pointer sanity check outside the
loop.
