mwifiex: 8997: fix the build warning 

Fix below build warning:
mlnux/moal_cfg80211.h:464:29: warning: large integer implicitly truncated to unsigned type [-Woverflow]
 #define REGULATORY_CFG_LEN  (NL80211_MAX_SUPP_REG_RULES << 1)
                             ^
mlinux/moal_sta_cfg80211.c:7711:42: note: in expansion of macro ‘REGULATORY_CFG_LEN’
  misc->param.custom_reg_domain.cfg_len = REGULATORY_CFG_LEN;

mlinux/moal_eth_ioctl.c: In function ‘woal_priv_set_get_scancfg’:
mlinux/moal_eth_ioctl.c:4144:2: warning: ISO C90 forbids variable length array ‘data’ [-Wvla]
  int data[arg_len];
