Subject: [PATCH] mtd: nand: fsl_ifc: remove unused variable

This one was accidentally introduced without any references,
and it causes a harmless warning:

drivers/mtd/nand/fsl_ifc_nand.c: In function 'fsl_ifc_read_page':
drivers/mtd/nand/fsl_ifc_nand.c:696:7: error: unused variable 'res' [-Werror=unused-variable]

Fixes: 79f40cc12fd3 ("mtd: nand: fsl_ifc: fix handing of bit flips in erased pages")
