platform/x86/intel/vsec: Fix xa_alloc memory leak

Browse source

Commit 936874b77d ("platform/x86/intel/vsec: Add PCI error recovery
support to Intel PMT") added an xarray to track the list of vsec devices to
be recovered after a PCI error. But it did not provide cleanup for the list
leading to a memory leak that was caught by kmemleak.  Do xa_alloc() before
devm_add_action_or_reset() so that the list may be cleaned up with
xa_erase() in the release function.
