Oliver Neukum e17ee48ce2 usb: gadget: printer: fix races against disable 
commit e587a7633dfee8987a999cf253f7c52a8e09276c upstream.

printer_read() and printer_write() guard against the race
against disable() by checking the dev->interface flag,
which in turn is guarded by a spinlock.
These functions, however, drop the lock on multiple occasions.
This means that the test has to be redone after reacquiring
the lock and before doing IO.

Add the tests.

This also addresses CVE-2024-25741

Fixes: 7f2ca14d2f9b9 ("usb: gadget: function: printer: Interface is disabled and returns error")
