nvme: make some sysfs diagnostic structures static

Building with C=1 generates the following warnings:
drivers/nvme/host/sysfs.c:397:25: warning: symbol 'dev_attr_io_errors' was not declared. Should it be static?
drivers/nvme/host/sysfs.c:444:30: warning: symbol 'nvme_ns_diag_attr_group' was not declared. Should it be static?
drivers/nvme/host/sysfs.c:1150:25: warning: symbol 'dev_attr_adm_errors' was not declared. Should it be static?

Make those structures static.
