brcmfmac: Fix memory leak in brcmf_p2p_create_p2pdev()

[ Upstream commit 5cc509aa83c6acd2c5cd94f99065c39d2bd0a490 ]

In the implementation of brcmf_p2p_create_p2pdev() the allocated memory
for p2p_vif is leaked when the mac address is the same as primary
interface. To fix this, go to error path to release p2p_vif via
brcmf_free_vif().
