Alexander Sverdlin 2ebc336be0 mtd: spi-nor: Check for zero erase size in spi_nor_find_best_erase_type()
Erase can be zeroed in spi_nor_parse_4bait() or
spi_nor_init_non_uniform_erase_map(). In practice it happened with
mt25qu256a, which supports 4K, 32K, 64K erases with 3b address commands,
but only 4K and 64K erase with 4b address commands.
