Olivier Maignial f5a0506067 mtd: spinand: winbond: Fix ecc_get_status 
Reading ECC status is failing.

w25n02kv_ecc_get_status() is using on-stack buffer for
SPINAND_GET_FEATURE_OP() output. It is not suitable for
DMA needs of spi-mem.

Fix this by using the spi-mem operations dedicated buffer
spinand->scratchbuf.

See
spinand->scratchbuf:
