This is odd, since we clearly cover all values for enum

Additionally, rename srp_wait_for_queuecommand() into
scsi_wait_for_queuecommand() and add a comment about the queuecommand()
call from scsi_send_eh_cmnd().
Note: this patch changes scsi_internal_device_block from a function that
did not sleep into a function that may sleep. This is fine for all
callers of this function:
* scsi_internal_device_block() is called from the mpt3sas device while
that driver holds the ioc->dm_cmds.mutex. This means that the mpt3sas
driver calls this function from thread context.
* scsi_target_block() is called by __iscsi_block_session() from
kernel thread context and with IRQs enabled.
* The SRP transport code also calls scsi_target_block() from kernel
thread context while sleeping is allowed.
* The snic driver also calls scsi_target_block() from a context from
which sleeping is allowed. The scsi_target_block() call namely occurs
immediately after a scsi_flush_work() call.

Currently slots are allocated from queues in a round-robin fashion.
This causes a problem for internal commands in device mode. For this
mode, we should ensure that the internal abort command is the last
command seen in the host for that device. We can only ensure this when
we place the internal abort command after the preceding commands for
device that in the same queue, as there is no order in which the host
will select a queue to execute the next command.
This queue restriction makes supporting scsi mq more tricky in
the future, but should not be a blocker.
Note: Even though v1 hw does not support internal abort, the
allocation method is chosen to be the same for consistency.
