Alexander Sverdlin a843699f16 mtd: spi-nor: Check for zero erase size in spi_nor_find_best_erase_type() ...

commit 2ebc336be08160debfe27f87660cf550d710f3e9 upstream.

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.
