Administration: Remove invalid attribute `maxlength` on `number` input.

Remove the `maxlength` attribute on screen options number of items per page input. Previously kept due to input inconsistencies in IE 11 and Edge, this invalid usage is no longer needed. IE 11 is no longer supported, and Edge now behaves according to specifications.
