NFC: fdp: Detect errors from fdp_nci_create_conn()
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.
Fixes: a06347c04c13e380 ("NFC: Add Intel Fields Peak NFC solution driver")
