Christophe Ricard 5a3570061a NFC: st21nfca: fix use of uninitialized variables in error path 
st21nfca_hci_load_session() calls kfree_skb() on unitialized
variables skb_pipe_info and skb_pipe_list if the call to
nfc_hci_connect_gate() failed. Reword the error path to not use
these variables when they are not initialized. While at it, there
seemed to be a memory leak because skb_pipe_info was only freed
once, after the for-loop, even though several ones were created
by nfc_hci_send_cmd.

Fixes: ec03ff1a8f
("NFC: st21nfca: Remove skb_pipe_list and skb_pipe_info
useless allocation")
