[PATCH] mtd: spinand: Wait after erase in spinand_markbad

[Emil Lenngren <emil.lenngren@xxxxxxxxx>]

SPI NAND flashes don't accept new commands while an erase is ongoing.
Make sure to wait until the device is ready before writing the marker.

Just as with the erase op, no error check is performed since we want
to continue writing the marker even if the erase fails.
