[ Upstream commit c1ed39ec116272935528ca9b348b8ee79b0791da ]
load_nls() take a char * parameter, use it to find nls module in list or construct the module name to load it.
This change make load_nls() take a const parameter, so we don't need do some cast like this:
ses->local_nls = load_nls((char *)ctx->local_nls->charset);
