nvmet: print namespace IDs as unsigned 32bit value

Browse source

struct nvmet_ns.nsid is a u32, but a few messages print it with %d.
An NSID larger than 0x7fffffff is rendered as a negative number, which
is misleading in general and particularly so for the configfs messages
that echo back the NSID the user just asked for.

For example:
[  T200] nvmet: adding nsid -16 to subsystem mysubsystem

Print them with %u. The invalid-NSID error in nvmet_ns_make() keeps its
%#x because the two values it rejects, 0 and NVME_NSID_ALL, are more
readable in hex format. No functional change other than how the NSID is
formatted.

Fixes: a07b4970f4 ("nvmet: add a generic NVMe target")
Fixes: c6925093d0 ("nvmet: Optionally use PCI P2P memory")
Fixes: 5a47c2080a ("nvmet: support reservation feature")
