ptp: kvm: x86: Return EOPNOTSUPP instead of ENODEV from kvm_arch_ptp_init()
[ Upstream commit 5e7aa97c7acf171275ac02a8bb018c31b8918d13 ]
The caller, ptp_kvm_init(), emits a warning if kvm_arch_ptp_init() exits
with any error which is not EOPNOTSUPP:
"fail to initialize ptp_kvm"
Replace ENODEV with EOPNOTSUPP to avoid this spurious warning,
aligning with the ARM implementation.
Fixes: a86ed2cfa13c ("ptp: Don't print an error if ptp_kvm is not supported")
