Suppose INI gDot11Mode is configured as 1 dot11mode_11a, but
the enum MLME_DOT11_MODE_ABG is defined at the last, which is
causing STA to connect in dot11mode_11ac.
So, lower dot11modes should be defined first. Change the order
of dot11mode_11abg to the initial enum value.
Change MLME dot11mode mapping to CSR dot11mode, passing to
csr_convert_mode_to_nw_type function.
