In pm8001_pci_resume(), the use of the u32 type for the local variable
device_state causes a sparse warning:

warning: incorrect type in assignment (different base types)
    expected unsigned int [usertype] device_state
    got restricted pci_power_t [usertype] current_state

Since this variable is used only once in the function, remove it and
use pdev->current_state directly. While at it, also add a blank line
after the last local variable declaration.
