[PATCH] block/merge: remove unnecessary min() with UINT_MAX

[Caleb Sander Mateos]

In bvec_split_segs(), max_bytes is an unsigned, so it must be less than
or equal to UINT_MAX. Remove the unnecessary min().

Prior to commit 67927d220150 ("block/merge: count bytes instead of
sectors"), the min() was with UINT_MAX >> 9, so it did have an effect.
