Christophe JAILLET f1e715d4a4 mtd: rawnand: meson: Fix a potential double free issue 
[ Upstream commit ec0da06337 ]

When meson_nfc_nand_chip_cleanup() is called, it will call:
	meson_nfc_free_buffer(&meson_chip->nand);
	nand_cleanup(&meson_chip->nand);

nand_cleanup() in turn will call nand_detach() which calls the
.detach_chip() which is here meson_nand_detach_chip().

meson_nand_detach_chip() already calls meson_nfc_free_buffer(), so we
could double free some memory.

Fix it by removing the unneeded explicit call to meson_nfc_free_buffer().
