Use 127 instead of CHAR_MAX for the limit on the sequence count. The
limit doesn't have anything to do with characters. The count mainly
needs to fit in the VOP_READ() ioflag after being left shifted by 16.
Moved vn_lock() before vn_closefile(). vn_lock() was mismerged from
Lite2.
Removed some gratuitous braces.
