brcmfmac: p2p: Deal with set but unused variables

'vif' is a function parameter which is oddly overwritten within the
function, but never read back.  'timeout' is set, but never checked.

Fixes the following W=1 kernel build warning(s):

 drivers/net/wireless/broadcom/brcm80211/brcmfmac/p2p.c: In function ‘brcmf_p2p_scan_prep’:
 drivers/net/wireless/broadcom/brcm80211/brcmfmac/p2p.c:894:31: warning: parameter ‘vif’ set but not used [-Wunused-but-set-parameter]
 drivers/net/wireless/broadcom/brcm80211/brcmfmac/p2p.c: In function ‘brcmf_p2p_tx_action_frame’:
 drivers/net/wireless/broadcom/brcm80211/brcmfmac/p2p.c:1549:6: warning: variable ‘timeout’ set but not used [-Wunused-but-set-variable]
