process_nlm_parameters: Process NLM parameters

Returns -1 for a request that needs processing, otherwise returns an NLM status

preq: passed in so interface doesn't need to change when NLM Client uses IP address exclusive: TRUE if lock is a write lock alock: nlm4_lock request structure plock: cache_lock_desc_t to fill in from alock ppentry: cache inode entry pointer to fill in pcontext: FSAL op context pclient: cache inode client care: TRUE if this caller cares if an owner is found (otherwise return NLM4_GRANTED because the caller will have nothing to do) ppnlm_client: NLM Client to fill in, returns a reference to the client ppowner: NLM Owner to fill in, returns a reference to the owner ppblock_data: Data required to make a call back to the client to grant a blocked lock
