libext2fs: fix regression in ext2fs_new_block2() for uninit_bg file systems 

Commit b0ecb787ef introduced a bug in check_block_uninit(), which is
used by ext2fs_new_block2().  This bug resulted in the block bitmap
for the block group in question not having space reserved for the file
system metadata blocks.
