Btfs: More metadata allocator optimizations

Browse source

This lowers the empty cluster target for metadata allocations.  The lower
target makes it easier to do allocations and still seems to perform well.

It also fixes the allocator loop to drop the empty cluster when things
start getting difficult, avoiding false enospc warnings.
