Subject: [PATCH v2] mtd: spi-nor: core: correct type of i

The i should be signed to find out the end of the loop. Otherwise,
i >= 0 is always true and loop becomes infinite. Make its type to be
int.

Fixes: 6a9eda34418f ("mtd: spi-nor: core: set mtd->eraseregions for non-uniform erase map")
Signed-off-by: Muhammad Usama Anjum <[email protected]>

Changes since v1:
- Make i int instead of u8
