mlxsw: spectrum_acl: Add cleanup after C-TCAM update error condition

When writing to C-TCAM, mlxsw driver uses cregion->ops->entry_insert().
In case of C-TCAM HW insertion error, the opposite action should take
place.
Add error handling case in which the C-TCAM region entry is removed, by
calling cregion->ops->entry_remove().
