mtd: spi-nor: sfdp: Fix wrong erase type bitmask for overlaid region
commit abdf5a5ef9652bad4d58058bc22ddf23543ba3e1 upstream.
At the time spi_nor_region_check_overlay() is called, the erase types are
sorted in ascending order of erase size. The 'erase_type' should be masked
with 'BIT(erase[i].idx)' instead of 'BIT(i)'.
