Subject: [PATCH v2] brcmfmac: replace one-element array with flexible-array member

One-element arrays are obsolete, and flexible
array members have taken their place. So, in
struct cca_stats_n_flags, replace the one-element
array with a flexible-array member.

This fixes warnings such as:
./drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c:119:6-9: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)
