Bluetooth: btintel_pcie: Clear automask on spurious interrupts
On spurious interrupt where the TX and RX causes are not set, driver was
not clearing the auto mask which can block all the interrupts. Driver
needs to clear the automask even if no causes are set.
Fixes: c2b636b3f788 ("Bluetooth: btintel_pcie: Add support for PCIe transport")
