wlan: Fix P2P GO slot time and hence EDCA params incorrect values
As part of slot time sessionization, a bug got introduced which sets the
slot time to long slot and EDCA params to mixed mode 11g instead of pure
11g when P2P GO comes up. This is because we removed the usage of CFG
for slot time and default slot time in CFG was 1 which was getting read
before; The fix is to set it explicitly during start bss based on
phyMode
