PCI: hotplug: pciehp: Fix possible race condition in writing slot
The slot control register is modified as follows:
(1) Read the register value
(2) Change the value
(3) Write the value to the register
Those must be done atomically, otherwise writing to control register
would cause an unexpected result.
