tty: vt: pass vc_resize_user as a parameter
It is pretty unfortunate to set vc_data::vc_resize_user in two callers
of vc_do_resize(). vc_resize_user is immediately reset there (while
remembering it). So instead of this back and forth, pass 'from_user' as
a parameter.
Notes on 'int user':
* The name changes from 'user' to 'from_user' on some places to be
consistent.
* The type is bool now as 'int user' might evoke user's uid or whatever.
Provided vc_resize() is called on many places and they need not to care
about this parameter, its prototype is kept unchanged. Instead, it is
now an inline calling a new __vc_resize() which implements the above.
This patch makes the situation much more obvious.
