qcacmn: Fix the incorrect check in is_service_enabled_tlv

Many firmware do not send wmi_ext_service bitmap in wmi_ready event
so the ext_service_bitmap will be empty in such cases. So the condition
in the is_service_enabled_tlv to check for wmi_ext_service bitmap
and return false is wrong as wmi_ext_service bitmap support is not
necessity. This condition leads to incorrect behavior in cases when
firmware do not support wmi_ext_service bitmap as is_service_enabled_tlv
returns false for every service.

Fix the above failure by addition of condition check for wmi_ext_service
bitmap only when wmi_ext2_service bitmap is supported by firmware.
