[PATCH 2/6] thinkpad-acpi: remove uneeded tp_features.hotkey tests in hotkey_exit

[Henrique de Moraes Holschuh <hmh@xxxxxxxxxx>]

hotkey_exit() is only called if hotkey_init() finished sucessfully, or
by direct calls inside hotkey_init().  The tp_features.hotkey test is
always true, and just adds to the confusion, remove it.  Also, avoid
calling hotkey_mask_set() when it won't do anything useful.
