[FIX] helpdesk_request_type: corrected bug on attachments in new ticket form

The param "max_upload_size" was missing when rendering "helpdesk_mgmt.portal_create_ticket".
Instead of added it, I've overloaded the response from helpdesk_mgmt create_new_ticket

helpdesk_request_type/controllers/main.py
