um: Remove BKL from mmapper
cycle_kernel_lock() was added during the big BKL pushdown. It should
ensure the serializiation against driver init code.
mmapper_open() cannot be called before misc_register() succeeded, but
p_buf might be uninitialized.
Move the initialization of p_buf before the misc_register() call and
get rid of cycle_kernel_lock().
