cluster/dht: rebalance min-free-disk fix
To calculate available space on a subvolume we used to do
the following in __dht_check_free_space.
post_availspace = (dst_statfs.f_bavail * dst_statfs.f_frsize) - stbuf->ia_size
Now to subtracting the file size from available space is tricky here.
Sometime available space will be lesser than the file size and since all the
participating members in calculation are unsigned int, the result is a large
number (integer overflow).
Solution: We do not need to subtract the file size from the space available,
since fallocate would have reserved file size space already.
