qcacld-3.0: Remove macro PMO_KEK_LEN_LEGACY

Currently,  macro is used instead of destination size
to copy KEK pmo_gtk_req to kck and kek of
WMI_GTK_OFFLOAD_CMD_fixed_param.

Fix is to Copy KEK bytes from pmo_gtk_req same as the size of
cmd->kek i.e destination address to avoid macro change if size
of cmd->kck changes in future.
