Long Li 41608b64b1 PCI: hv: Fix sleep while in non-sleep context when removing child devices from the bus 
In hv_pci_bus_exit, the code is holding a spinlock while calling
pci_destroy_slot(), which takes a mutex.

This is not safe for spinlock. Fix this by moving the children to be
deleted to a list on the stack, and removing them after spinlock is
released.

Fixes: 94d2276320 ("PCI: hv: Fix a race condition when removing the device")
