NFC: st21nfca: Fix scripts/checkpatch.pl warnings "Missing a blank line after declarations"

Fixing scripts/checkpatch.pl warning "Missing a blank line after declarations" in:
- st21nfca.c:
	- check_presence after fwi variable declaration.
	- get_frame_size after len variable declaration.
	- st21nfca_hci_i2c_repack after "i, j, r, size" variable declaration.

- st21nfca_dep.c st21nfca_tx_work after skb pointer declaration.
