Subject: [PATCH wireless 3/9] wifi: cfg80211: avoid garbage value of 'noise' in brcmf_cfg80211_dump_survey()

brcmf_fil_cmd_int_get() reads the value of 'noise' and passes it to
brcmf_fil_cmd_data_get(). Initialize 'noise' to avoid garbage value.

Fixes: 6c04deae1438 ("brcmfmac: Add dump_survey cfg80211 ops for HostApd AutoChannelSelection")
