usb: gadget: f_mass_storage: Disable eps during disconnect

When trying two ums commands in a row, the second one no longer
enumerates properly from the host.

This happens since commit
59310d1ecb9f ("usb: gadget: introduce 'enabled' flag in struct usb_ep")
causing usb_ep_enable() to return early when ep->enabled is already set.

Gadget function drivers (such as f_fastboot or f_mass_storage) implement
a disable() function which is called whenever we are done using the
gadget.

Because f_mass_storage driver does not disable the endpoints,
ep->enabled will never be set to false again.

This can be reproduced on the STM32MP157C-DK2 or the Khadas VIM3 boards.

Add calls to usb_ep_disable() as done in linux [1] to fix this.
