textsearch: fix Boyer-Moore text search bug
Upstream commit aebb6a849cfe7d89bcacaaecc20a480dfc1180e7
The current logic has a bug which cannot find matching pattern, if the
pattern is matched from the first character of target string.
for example:
pattern=abc, string=abcdefg
pattern=a, string=abcdefg
Searching algorithm should return 0 for those things.
