qcacmn: Address NULL pointer reference in scm_11d_handle_country_info()

When a 2G AP vap is brought up on a "WORLD" regdomain (say 0x30),
reg_is_world_alpha2() returns true. Also "enable_11d_in_world_mode" is set
true by default during reg psoc creation. When a regdomain is set, process
master channel list is invoked during which "enable_11d_supp" is set to
true as regdomain is "WORLD" and "enable_11d_in_world_mode" is also set to
true.

As "reg_11d" is enabled, during beacon and probe processing, country
update is done and scm_11d_handle_country_info() is called. 11d feature is
specific to MCL and hence on WIN code base, it causes invalid memory
access and it panics.

"enable_11d_in_world_mode" is MCL specific feature and is disabled for WIN
to avoid any call to scm_11d_handle_country_info for WIN codebase.
