[XFS] Make xfs_alloc_compute_aligned() void.

Browse Source 
xfs_alloc_compute_aligned() returns a value based on a comparison of the
computed extent length and the minimum length allowed. This is only used
by some callers - the other four return parameters are used more often.
Hence move the comparison to the code that actually needs to do it and
make xfs_alloc_compute_aligned() a void function.
