drm/xe/pf: Move VFs reprovisioning to worker

[ Upstream commit a4d1c5d0 ]

Since the GuC is reset during GT reset, we need to re-send the
entire SR-IOV provisioning configuration to the GuC. But since
this whole configuration is protected by the PF master mutex and
we can't avoid making allocations under this mutex (like during
LMEM provisioning), we can't do this reprovisioning from gt-reset
path if we want to be reclaim-safe. Move VFs reprovisioning to a
async worker that we will start from the gt-reset path.
