Bluetooth: btintel_pcie: avoid unguarded 64-bit division

From: Arnd Bergmann <[email protected]>

Directly dividing a 64-bit value is not allowed on 32-bit architectures in the kernel.

arm-linux-gnueabi/bin/arm-linux-gnueabi-ld: drivers/bluetooth/btintel_pcie.o: in function `btintel_pcie_suspend_late':
btintel_pcie.c:(.text+0x224): undefined reference to `__aeabi_ldivmod'

Since this is a ktime_t value and dividing by 1000 gives a microsecond number, just convert it into microseconds using the appropriate helper.
