freezer: Have {,un}lock_system_sleep() save/restore flags
Rafael explained that the reason for having both PF_NOFREEZE and
PF_FREEZER_SKIP is that {,un}lock_system_sleep() is callable from
kthread context that has previously called set_freezable().
In preparation of merging the flags, have {,un}lock_system_slee() save
and restore current->flags.
