mainlining shenanigans

Incorrect value of the running_req was causing the driver unload to be stuck during the SAS lldd_dev_gone notification handling. During SATA I/O completion, for some error status values, the driver schedules the event handler and running_req is decremented from that. However, there are some other error status values (like IO_DS_IN_RECOVERY, IO_XFER_ERR_LAST_PIO_DATAIN_CRC_ERR) where the I/O has already been completed by fw/driver so running_req is not decremented. Also during NCQ error handling, driver itself will initiate READ_LOG_EXT and ABORT_ALL. When libsas/libata initiate READ_LOG_EXT (0x2F), driver increments running_req. This will be completed by the driver in pm80xx_chip_sata_req(), but running_req was not decremented.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
