MInimum size of mpp subdomain uncorrectly set for AGRIF zooms

Description
Context
AGRIF does not work for too small mpp subdomains (defined as the sum of the ghosts cells + the sponge layer width + one line/column of zeros)
Analysis
Uncomplete stop statement in agrif_nemo_init
Recommendation
Modify stop in agrif_user routine such that:
jpi/jpj > 1 + nbghostcells + (nn_sponge_len * raf + 1)
e.g., since nn_sponge = 2 and nbghost = 3, if raf=1 (as in the 1st zoom of AGRIF_DEMO reference configuration), jpi/jpj > 7
This restriction will be relaxed in the forthcoming release.
