mtd: rawnand: mtk: Fix init error path

Browse Source 
[ Upstream commit 2073ae37d5 ]

Reviewing a series converting the for_each_chil_of_node() loops into
their _scoped variants made me realize there was no cleanup of the
already registered NAND devices upon error which may leak memory on
systems with more than a chip when this error occurs. We should call the
_nand_chips_cleanup() function when this happens.
