ufs: fix truncated values handling 64 bit metadata
Originally i_lastfrag was 32 bits but then we added support for handling
64 bit metadata and it became a 64 bit variable. That was during 2007, in
54fb996ac15c "[PATCH] ufs2 write: block allocation update". Unfortunately
these casts got left behind so the value got truncated to 32 bit again.
