mtd: rawnand: hynix: fixed typo

[ Upstream commit 6819db94e1cd3ce24a432f3616cd563ed0c4eaba ]

The function hynix_nand_rr_init() should probably return an error code.
Judging by the usage, it seems that the return code is passed up
the call stack.
Right now, it always returns 0 and the function hynix_nand_cleanup()
in hynix_nand_init() has never been called.
