NFC: fdp: Detect errors from fdp_nci_create_conn()

Browse Source 
drivers/nfc/fdp/fdp.c: In function ‘fdp_nci_patch_otp’:
drivers/nfc/fdp/fdp.c:373: warning: comparison is always false due to limited range of data type
drivers/nfc/fdp/fdp.c: In function ‘fdp_nci_patch_ram’:
drivers/nfc/fdp/fdp.c:444: warning: comparison is always false due to limited range of data type

fdp_nci_create_conn() may return a negative error code, which is
silently ignored by assigning it to a u8.

Change conn_id from u8 to int to fix this.
