The sort__has_comm variable is to check whether the comm sort key is
given. This is necessary to support thread filtering in the TUI hists
browser later.

The commit 2eafd410e669 ("perf hists browser: Only 'Zoom into thread'
only when sort order has 'pid'") disabled thread filtering in hist
browser for the default sort key. However the he->thread is still valid
even if 'pid' sort key is not given. Only thing it should not use is
the pid (or tid) of the thread. So allow to filter by thread when
'comm' sort key is given and show pid only if 'pid' sort key is given.

The context menu in TUI hists browser checks corresponding sort keys
when creating the menu item. But hotkey actions lacks these checks so
it can filter using incorrect info.
For example, default sort key of 'perf top' doesn't contain 'comm' or
'pid' sort key so each hist entry's thread info is not reliable. Thus
it should prohibit using thread filter on 't' key.

perf hists browser: Check sort keys before hot key actions
The context menu in TUI hists browser checks corresponding sort keys
when creating the menu item. But hotkey actions lacks these checks so
it can filter using incorrect info.
For example, default sort key of 'perf top' doesn't contain 'comm' or
'pid' sort key so each hist entry's thread info is not reliable. Thus
it should prohibit using thread filter on 't' key.
