Re: [PATCH (BUGFIX)] gitweb: Fix two 'uninitialized value' varnings in git_tree()

If we did try to access nonexistent directory or file, which means
that git_get_hash_by_path() returns `undef`, uninitialized $hash
variable was passed to 'open' call.  Now we fail early with "404 Not
Found - No such tree" error.  (If we try to access something which
does not resolve to tree-ish, for example a file / 'blob' object, the
error will be caught later, as "404 Not Found - Reading tree failed"
error).

If we tried to use 'tree' action without $file_name ('f' parameter)
set, which means either tree given by hash or a top tree (and we
currently cannot distinguish between those two cases), we cannot print
path breadcrumbs with git_print_page_path().  Fix this by moving call
to git_print_page_path() inside conditional.

BTW. should we use "No such tree" or "No such directory".

I prefer the former.
