megaraid_sas: Move poll_aen_lock initializer
commit bd8d6dd43a77bfd2b8fef5b094b9d6095e169dee upstream.
The following patch moves the poll_aen_lock initializer from
megasas_probe_one() to megasas_init(). This prevents a crash when a user
loads the driver and tries to issue a poll() system call on the ioctl
interface with no adapters present.
