pm_qos: remove BKL
pm_qos_power_open got its lock_kernel() calls from the open() pushdown. A
look at the code shows that the only global resources accessed are
pm_qos_array and "name". pm_qos_array doesn't change (things pointed to
therein do change, but they are atomics and/or are protected by
pm_qos_lock). Accesses to "name" are totally unprotected with or without
the BKL; that will be fixed shortly. The BKL is not helpful here; take it
out.
