fsp: Bail out of HIR if FSP is resetting voluntarily
a. Surveillance response times out and OPAL triggers a HIR
b. Before the HIR process kicks in, OPAL gets a PSI interrupt indicating link down
c. HIR process continues and OPAL tries to write to DRCR; PSI link inactive => xstop
OPAL should confirm that the FSP is not already in reset in the HIR path.
[V2] Handle the case where a second reset is triggered due to the two resets
happening in succession.
