fs/ocfs2/journal.h: add bits_wanted while calculating credits in ocfs2_calc_extend_credits
While adding extends to a file, the credits are calculated incorrectly
and if the requested clusters is more than one (or more because we used
a conservative limit) then we run out of journal credits and we hit an
assert in journalling code.
The function parameter bits_wanted variable was not used at all.
