[PATCH] ext2: block allocation fix

Patch from Alex Tomas <bzzz@tmi.comex.ru>

There is a logic error in ext2_new_block().  If we manage to reserve some
blocks in the final blockgroup, local variable `bit' will be equal to
sbi->s_groups_count and we erroneously assume that the allocation failed.

Fix that up by testing local variable `group_alloc' instead.
