[PATCH] dm-multipath: fix get_word return value when the last word is found

[Vaughan Cao <vaughan.cao@oracle.com>]

get_word() returns how many bytes it has parsed when it gets a new word.
But the deleted code will cause 0 returned for the last word, which
breaks this semantic. It hasn't cause any trouble yet because we have
been calling it as we are certain there is an word left.
