mtd: nand: gpmi: Fix gpmi_nand_init() error path

The GPMI driver is wrongly assuming that nand_release() can safely be
called on an uninitialized/unregistered NAND device.

Add a new err_nand_cleanup label in the error path and only execute if
nand_scan_tail() succeeded.

Note that we now call nand_cleanup() instead of nand_release()
(nand_release() is actually grouping the mtd_device_unregister() and
nand_cleanup() in one call) because there's no point in trying to
unregister a device that has never been registered.
