Do not require the presence of `$balanced_parens` to get the commit SHA;
this allows a `Fixes: deadbeef` tag to get a correct suggestion rather
than a suggestion containing a reference to HEAD.
Given this patch:
: From: Tamir Duberstein <tamird@xxxxxxxxx>
: Subject: Test patch

: This is a test patch.

Before:
WARNING: Please use correct Fixes: style 'Fixes: <12 chars of sha1> ("<title line>")' - ie: 'Fixes: c10a7d25e68f ("Test patch")'
After:
WARNING: Please use correct Fixes: style 'Fixes: <12 chars of sha1> ("<title line>")' - ie: 'Fixes: bd17e036b495 ("checkpatch: warn for non-standard fixes tag style")'
The prior behavior incorrectly suggested the patch's own SHA and title
line rather than the referenced commit's. This fixes that.
Ironically this:
Fixes: bd17e036b495 ("checkpatch: warn for non-standard fixes tag style")
