Subject: [PATCH net-next] net: nci: remove set-but-not-used variable 'status'

gcc warning this:
net/nfc/nci/hci.c:373:5:
 warning: variable 'status' set but not used [-Wunused-but-set-variable]

It not used since commit d8cd37ed2fc8 ("NFC: nci: Fix improper
management of HCI return code"), so can be removed.
