[PATCH] usb: gadget: fix max_segment_size malformed table

[Randy Dunlap <rdunlap@infradead.org>]

Sphinx reports a malformed table due to the table begin/end line
segments being too short for the word "max_segment_size", so
extend them by one more '=' character to prevent to error.

Documentation/usb/gadget-testing.rst:459: ERROR: Malformed table.
Text in column margin in table line 9.

Fixes: 1900daeefd3e ("usb: gadget: ncm: Add support to update wMaxSegmentSize via configfs")
