USB: serial: sierra: fix potential deadlock at close
commit e60870012e5a35b1506d7b376fddfb30e9da0b27 upstream.
The portdata spinlock can be taken in interrupt context (via
sierra_outdat_callback()).
Disable interrupts when taking the portdata spinlock when discarding
deferred URBs during close to prevent a possible deadlock.
