Log Message:
nvme(4): don't write to INTMC register if in intx mode

this matches the handling of INTMS, both of which have the same
restrictions on access in MSI-X mode.

ideally, this register should be written to with a full set of
values for MSI (upto 32 bits), but trying to force MSI mode for
my test machine makes the system unstable.

tested with samsung SM981 256GB, samsung 980 PRO 1TB, and intel
760p 250G.
