ext2: don't set *count in the case of failure in ext2_try_to_allocate()
Currently we set *count to num(value 0) in the failure
of block allocation in ext2_try_to_allocate(). Without
reservation, we reuse *count(value 0) to retry block
allocation and wrong *count will cause only allocating
maximum 1 block even though having sufficent free blocks
in that block group. Finally, it probably cause significant
fragmentation.
