Subject: nfc: st21nfca: Fix static checker warning

From: Christophe Ricard <[email protected]>

commit b58afe6d6d3a53af165d5946f12c4b08c95acd58 upstream.

Fix static checker warning:
drivers/nfc/st21nfca/i2c.c:530 st21nfca_hci_i2c_acpi_request_resources()
error: 'gpiod_ena' dereferencing possible ERR_PTR()

Fix so that if no enable gpio can be retrieved an -ENODEV is returned.
