[PATCHv2 2/2] gitweb: clean up gitweb_check_feature() calls

[Giuseppe Bilotta <giuseppe.bilotta@gmail.com>]

Since git_check_feature now returns a scalar, the parentheses around the
variables initialized from gitweb_check_feature() are not needed.

We remove them for stylistic consistency and to prevent unnecessary
ambiguity in the code.

Fixed the commit message, use this instead of the previous one.
