percpu-refcount: cosmetic updates
* s/percpu_ref_release/percpu_ref_func_t/ as it's customary to have _t
postfix for types and the type is gonna be used for a different type
of callback too.
* Add @ARG to function comments.
* Drop unnecessary and unaligned indentation from percpu_ref_init()
function comment.
