qcacld-3.0: Fix uninitialized scalar variable

Issue1:wlan_hdd_set_mlo_ps function returns uninitialized
status on condition of being all link_adapters as
NULL from mlo_adapter_info.
Fix:initialize status varible with -EINVAL.

Issue2:hdd_regulatory_init API updates regulatory alpha2
from uninitialized alpha2 array.
Fix:initialize alpha2 array with 0.
