staging: r8188eu: Fix Smatch off-by-one warning in hal/rtl8188e_hal_init.c
Smatch reports the following warning:
"drivers/staging/rtl8188eu/hal/rtl8188e_hal_init.c:2008
Hal_ReadPowerValueFromPROM_8188E()
error: buffer overflow 'pwrInfo24G->IndexBW40_Base[rfPath]' 5 <= 5"
drivers/staging/rtl8188eu/hal/rtl8188e_hal_init.c
2005 /* 2.4G default value */
2006 for (group = 0; group < MAX_CHNL_GROUP_24G; group++) {
2007 pwrInfo24G->IndexCCK_Base[rfPath][group] = EEPROM_DEFAULT_24G_INDEX;
2008 pwrInfo24G->IndexBW40_Base[rfPath][group] = EEPROM_DEFAULT_24G_INDEX;
The reason is that IndexCCK_Base[] has MAX_CHNL_GROUP_24G elements, but
IndexBW40_Base is smaller by 1. Make them both have MAX_CHNL_GROUP_24G
elements.
