SCSI: Fix NULL pointer dereference in RTPM of block layer
The routines in scsi_pm.c assume that if a runtime-PM callback is
invoked for a SCSI device, it can only mean that the device's driver
has asked the block layer to handle the runtime power management (by
calling blk_pm_runtime_init(), which

This reverts commit 49718f0fb8c9 ("SCSI: Fix NULL pointer dereference in
runtime PM")
The old commit may lead to a issue that blk_{pre|post}_runtime_suspend and
blk_{pre|post}_runtime_resume can not be called in pairs.

Commit 991de2e59090 ("PCI, x86: Implement pcibios_alloc_irq() and
pcibios_free_irq()") changes the way to allocate PCI legacy IRQ
for PCI devices on x86 platforms. Instead of allocating PCI legacy
IRQs when pcibios_enable_device() gets called, now pcibios_allo
This helps improving the latency of small packets.

The value of the parameter is never re-read by the driver,
so a new value is ignored. Let know the user he
can't modify it by removing writable attribute.
