Subject: [PATCH v2] mtd: rawnand: brcmnand: Fix NULL pointer assignment

Sparse complained about the following:

drivers/mtd/nand/raw/brcmnand/brcmnand.c:921:40: warning: Using plain integer as NULL pointer

fix this issue by assigning the pointer to NULL.

Fixes: c1ac2dc34b51 ("mtd: rawnand: brcmnand: When oops in progress use pio and interrupt polling")
