mtd: rawnand: cafe: Fix a resource leak in the error handling path of 'cafe_nand_probe()'
A successful 'init_rs_non_canonical()' call should be balanced by a
corresponding 'free_rs()' call in the error handling path of the probe, as
already done in the remove function.
Update the error handling path accordingly.
Fixes: 8c61b7a7f4d4 ("[MTD] [NAND] Use rslib for CAFÉ ECC")
