drm/i915/selftests: Fix return value check in live_breadcrumbs_smoketest()

Browse Source 
[ Upstream commit 10c1f0cbcea93beec5d3bdc02b1a3b577b4985e7 ]

In case of error, the function live_context() returns ERR_PTR() and never
returns NULL. The NULL test in the return value check should be replaced
with IS_ERR().

Fixes: 52c0fdb25c ("drm/i915: Replace global breadcrumbs with per-context interrupt tracking")
