This function should return 0 on error.  Returning -1 would cause a
crash.

Also there is an extra space before the newline character and a missing
space between the "for" and the "mgmt_invalidate_icds".  I put the string
on one line.  The current version of checkpatch.pl complains that the
line is too long, but it makes grepping easier.

Stanse found that one error path in mgmt_invalidate_icds omits to unlock
ctrl->mbox_lock. Fix that.

Added in 756d29c8 (Enable async mode for mcc rings)
where the spinlock was moved.

This fix allows the driver to load when the FW allows more cids
than than the driver supports. The driver will limit the number of cid
to what it can support. There was no reason to fail the driver load,so,
