mtd: rawnand: marvell: prevent harmless warnings
Since the addition of WARN_ON() in nand_subop_get_data/addr_len()
helpers, this driver will produce harmless warnings (mostly at probe)
just because it always calls the nand_subop_get_data_len() helper in
the parsing function (even on non-data instructions, where this value
is meaningless and unneeded).
Fix these warnings by deriving the length only when it is relevant.
Fixes: 760c435e0f85 ("mtd: rawnand: make subop helpers return unsigned values")
