Correct the documentation of NAN vendor command

Present implementation of NAN vendor command does not use
attribute encapsulation for sending the command from userspace
to the driver, payload is directly sent as is. Attribute
QCA_WLAN_VENDOR_ATTR_NAN is used only for receiving vendor
events in the userspace from the driver. Update the doc as per
this implementation.
