reiserfs: remove first_zero_hint
The first_zero_hint metadata caching was never actually used, and it's of
dubious optimization quality. This patch removes it.
It doesn't actually shrink the size of the reiserfs_bitmap_info struct, since
that doesn't work with block sizes larger than 8K. There was a big fixme in
there, and with all the work lately in allowing block size > page size, I
might as well kill the fixme as well.
