[PATCH 2/2] accel/amdxdna: Reduce log noise during process termination

[Mario Limonciello <mario.limonciello@amd.com>]

During process termination, several error messages are logged that are
not actual errors but expected conditions when a process is killed or
interrupted. This creates unnecessary noise in the kernel log.

The specific scenarios are:

1. HMM invalidation returns -ERESTARTSYS when the wait is interrupted by
   a signal during process cleanup. This is expected when a process is
   being terminated and should not be logged as an error.

2. Context destruction returns -ENODEV when the firmware or device has
   already stopped, which commonly occurs during cleanup if the device
   was already torn down. This is also an expected condition during
   orderly shutdown.

Downgrade these expected error conditions from error level to debug level
to reduce log noise while still keeping genuine errors visible.

Fixes: 97f27573837e ("accel/amdxdna: Fix potential NULL pointer dereference in context cleanup")
