nfc: constify nci_ops
The struct nci_ops is modified by NFC core in only one case:
nci_allocate_device() receives too many proprietary commands (prop_ops)
to configure. This is a build time known constrain, so a graceful
handling of such case is not necessary.
Instead, fail the nci_allocate_device() and add BUILD_BUG_ON() to places
which set these.
This allows to constify the struct nci_ops (consisting of function
pointers) for correctness and safety.
