Don't examine ACPI_STA_ENABLE bit of device's_STA object on initial

Browse source 
state.  Instead, use ACPI_STA_PRESENT and ACPI_STA_FUNCTIONAL for it.
In some ACPI BIOS implementations, boot disabled devices don't have
ACPI_STA_ENABLE bit in _STA object.
Also it is not fatal if getting current IRQ of boot disabled devices
is failed in initial state.

And minor fixes.
