CLEANUP: proxy: Remove dead code when parsing "http-restrict-req-hdr-names" option

negation or default modifiers are not supported for this option. However,
this was already tested earlier in cfg_parse_listen() function. Thus, when
"http-restrict-req-hdr-names" option is parsed, the keyword modifier is
always equal to KWM_STD. It is useless to test it again at this place.

This patch should solve the issue #1702.
