usb: gadget: f_mass_storage: Fix Bulk-only RESET handling
The ep0 request tag was not recorded thus resulting in phase
problems while sending status/response in handle_execption() handler.
This was resulting in MSC compliance test failures with USBCV tool.
With this patch, the Bulk-Only Mass storage RESET request is
handled correctly and the MSC compliance tests pass.
(cherry picked from commit 73ee4da994e7b97bd8241e39099cf3dd94675d79)
