mlxsw: spectrum_buffers: Forbid configuration of multicast pool 

Commit e83c045e53 ("mlxsw: spectrum_buffers: Configure MC pool") added
a dedicated pool for multicast traffic. The pool is visible to the user
so that it would be possible to monitor its occupancy, but its
configuration should be forbidden in order to maintain its intended
operation.
