NFC: st21nfca: Fix memory leak in device probe and remove
'phy->pending_skb' is alloced when device probe, but forgot to free
in the error handling path and remove path, this cause memory leak
as follows:
unreferenced object 0xffff88800bc06800 (size 512):
comm "8", pid 11775, jiffies 4295159829 (age 9.032s)
hex dump (first 32 bytes):

Fix it by freeing 'pending_skb' in error and remove.
