Subject: [PATCH 4/8] staging: vchiq_core: Lower indentation of a conditional block

Lower indentation of 'if (bulk->data && service->instance)'
conditional block. This is achieved introducing a early check for
(!bulk->data || !service->instance) and using a goto label 'complete'
if it evaluates to true.

No functional changes intended in this patch.
