maint: src/dfasearch.c: remove unnecessary re_set_syntax call

[Jim Meyering]

FYI, I've just pushed the following small change, found by inspection:

  maint: src/dfasearch.c: remove unnecessary re_set_syntax call
  * src/dfasearch.c (GEAcompile): Don't call "re_set_syntax (syntax_bits)"
  just before regex_compile; that function does the same thing already.
