gitweb: Remove parse_from_to_diffinfo code from git_patchset_body

In commit 9092174
  "gitweb: Split git_patchset_body into separate subroutines"
a part of git_patchset_body code was separated into parse_from_to_diffinfo
subroutine.  But instead of replacing the separated code by the call to
mentioned subroutine, the call to subroutine was placed before the separated
code.  This patch removes parse_from_to_diffinfo code from git_patchset_body
subroutine.
