[PATCH] virtio_pci_modern: replace msleep(1) with usleep_range(1000, 2000)

[Mirza Ishan Beg]

Replace msleep(1) with usleep_range(1000, 2000) in the queue reset
loops.
msleep(1) relies on jiffies and can sleep up to 4-10 ms depending on HZ,
whereas usleep_range provides predictable microsecond-level delay.
