NFC: nci: Move NFCEE discovery logic 

NFCEE_DISCOVER_CMD is a specified NCI command used to discover
NFCEE IDs.
Move nci_nfcee_discover() call to nci_discover_se() in order to
guarantee:
- NFCEE_DISCOVER_CMD run when the NCI state machine is initialized
- NFCEE_DISCOVER_CMD is not run in case there is not discover_se
  hook defined by a NFC device driver.
