counter: 104-quad-8: Return error when invalid mode during ceiling_write
[ Upstream commit 728246e ] The 104-QUAD-8 only has two count modes where a ceiling value makes sense: Range Limit and Modulo-N. Outside of these two modes, setting a ceiling value is an invalid operation -- so let's report it as such by returning -EINVAL.
