percpu_ref: restructure operation mode switching
Restructure atomic/percpu mode switching.
* The users of __percpu_ref_switch_to_atomic/percpu() now call a new
function __percpu_ref_switch_mode() which calls either of the
original switching functions depending on the current state of
ref->force_atomic and the __PERCPU_REF_DEAD flag. The callers no
longer check whether switching is necessary but always invoke
__percpu_ref_switch_mode().
* !ref->confirm_switch waiting is collected into
__percpu_ref_switch_mode().
This patch doesn't cause any behavior differences.
