Subject: [PATCH] NFC: nci: Fix error check of nci_hci_create_pipe() result

net/nfc/nci/hci.c: In function ‘nci_hci_connect_gate’:
net/nfc/nci/hci.c:679: warning: comparison is always false due to limited range of data type

In case of error, nci_hci_create_pipe() returns NCI_HCI_INVALID_PIPE,
and not a negative error code.

Correct the check to fix this.
