scsi: device_handler: alua: Remove a might_sleep() annotation
The might_sleep() annotation in alua_rtpg_queue() is not correct since the
command completion code may call this function from atomic context.
Calling alua_rtpg_queue() from atomic context in the command completion
path is fine since request submitters must hold an sdev reference until
command execution has completed. This patch fixes the following kernel
complaint:
BUG: sleeping function called from invalid context at drivers/scsi/device_handler/scsi_dh_alua.c:992
