mtd: nand: Fix regression in BBM detection

Commit c7b28e25cb9beb943aead770ff14551b55fa8c79 ("mtd: nand: refactor BB
marker detection") caused a regression in detection of factory-set bad
block markers, especially for certain small-page NAND. This fix removes
some unneeded constraints on using NAND_SMALL_BADBLOCK_POS, making the
detection code more correct.

This regression can be seen, for example, in Hynix HY27US081G1M and
similar.
