[PATCH 1/2] drm/amdkfd: Move queue fs deletion after destroy check

[Kent Russell]

We were removing the kernfs entry for queue info before checking if the
queue could be destroyed. If it failed to get destroyed (e.g. during
some GPU resets), then we would try to delete it later during pqm
teardown, but the file was already removed. This led to a kernel WARN
trying to remove size, gpuid and type. Move the remove to after the
destroy check.
