Remove debug logging "Processing tile:..."

[letmaik]

At some point we added the following log statement:

wps/geogrid/src/process_tile_module.F

Lines 198 to 199 in d7530d0

	call mprintf(.true.,LOGFILE, "Processing tile: minx=%i maxx=%i miny=%i maxy=%i", &
	i1=dummy_start_patch_i, i2=dummy_end_patch_i, i3=dummy_start_patch_j, i4=dummy_end_patch_j)

And here:

wps/metgrid/src/process_domain_module.F

Lines 319 to 320 in d7530d0

	call mprintf(.true.,LOGFILE, "Processing tile: minx=%i maxx=%i miny=%i maxy=%i", &
	i1=my_minx, i2=my_maxx, i3=my_miny, i4=my_maxy)

This was only used for debugging and should probably be removed again.
