When building with -Wextra, we get a lot of warnings for the lpfc driver

drivers/scsi/lpfc/lpfc_attr.c:2786:77: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits]

drivers/scsi/lpfc/lpfc_attr.c:3064:1930: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits]
The code works as intended, but it would be nice to shut up the warning
so we don't clutter up build logs with this. Using a separate inline
function for it makes it clear to the compiler that the comparison is
necessary in the caller but still lets it do the constant-folding.

I wish the OSD code could simply use blk_rq_map_* helpers like
everyone else, but the complex nature of deciding if we have
DATA IN and/or DATA OUT buffers might make this impossible
(at least for a mere human like me).
But using blk_rq_append_bio at least allows sharing the setup code
between request with or without dat a buffers, and given that this
is the last user of blk_make_request it allows getting rid of that
somewhat awkward interface.

The SA controller spins down RAID drive spares.
A REGNEWD event causes an inquiry to be sent to all physical
drives. This causes the SA controller to spin up the spare.
The controller suspends all I/O to a logical volume until
the spare is spun up. The spin-up can take over 50 seconds.
This can result in one or both of the following:
- SML sends down aborts and resets to the logical volume
and can cause the logical volume to be off-lined.
- a negative impact on the logical volume's I/O performance
each time a REGNEWD is triggered.
