NFC: nci: Use __nci_request for exported routines
Since we do not know in which context drivers will call these routines, they should use the unlocked version of nci_request, i.e. __nci_request. It is up to drivers to know/decide if they need to take the req_lock mutex before calling those routines. When being called from the NCI setup routine there is no need to do so as ops->setup is called under req_lock. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
