drm/amd/ras: record the fatal state on every device of the hive

Browse source

The fatal error interrupt is broadcast to every device of the hive and
they all race for amdgpu_ras_global_ras_isr(), which hands -EBUSY to
everyone but the winner. Treating that as a failure returns before the
device is marked, so seven devices out of eight are left without their
fatal and SRAM ECC state, the one that actually logged the error among
them. KFD then tells the processes on those devices that the reset was
a plain hang.

-EBUSY only means the reset has already been asked for. Record the
state anyway and leave the request to the winner.
