jump_label: use ATOMIC_INIT() for initialization of .enabled
Currently ATOMIC_INIT() is not used because in the past that macro was
provided by linux/atomic.h which is not usable from linux/jump_label.h.
However since commit 7ca8cf5347f7 ("locking/atomic: Move ATOMIC_INIT
into linux/types.h") the macro only requires linux/types.h.
Remove the now unnecessary workaround and the associated assertions.
