ice: fix pin phase adjust updates on PF reset
Do not allow to set phase adjust value for a pin if PF reset is in
progress, this would cause confusing netlink extack errors as the firmware
cannot process the request properly during the reset time.
Return (-EBUSY) and report extack error for the user who tries configure
pin phase adjust during the reset time.
Test by looping execution of below steps until netlink error appears:
- perform PF reset
$ echo 1 > /sys/class/net/<ice PF>/device/reset
- change pin phase adjust value:
$ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml \
--do pin-set --json '{"id":0, "phase-adjust":1000}'
Fixes: 90e1c90750d7 ("ice: dpll: implement phase related callbacks")
