Christophe JAILLET f4b700c718 mtd: rawnand: fsl_upm: Fix an off-by one test in fun_exec_op() 
[ Upstream commit c6abce6033 ]

'op-cs' is copied in 'fun->mchip_number' which is used to access the
'mchip_offsets' and the 'rnb_gpio' arrays.
These arrays have NAND_MAX_CHIPS elements, so the index must be below this
limit.

Fix the sanity check in order to avoid the NAND_MAX_CHIPS value. This
would lead to out-of-bound accesses.
