brcmfmac: check memory allocation in brcmf_add_if()

For P2P_DEVICE interface the struct brcmf_if instance is
allocated using kzalloc() which can fail. Add pointer
check and return -ENOMEM if it failed. Fixes the following
smatch error:

"drivers/net/wireless/brcm80211/brcmfmac/dhd_linux.c:770
brcmf_add_if()
  error: potential null dereference 'ifp'. (kzalloc returns null)"
