The following was seen with CMF enabled:

BUG: using smp_processor_id() in preemptible
code: systemd-udevd/31711
kernel: caller is lpfc_update_cmf_cmd+0x214/0x420  [lpfc]
kernel: CPU: 12 PID: 31711 Comm: systemd-udevd
kernel: Call Trace:
kernel: <TASK>
kernel: dump_stack_lvl+0x44/0x57
kernel: check_preemption_disabled+0xbf/0xe0
kernel: lpfc_update_cmf_cmd+0x214/0x420 [lpfc]
kernel: lpfc_nvme_fcp_io_submit+0x23b4/0x4df0 [lpfc]

this_cpu_ptr() calls smp_processor_id() in a preemptible context.

Fix by using per_cpu_ptr() with raw_smp_processor_id() instead.
