Casey Chen 251ef6f71b nvme-pci: do not call nvme_dev_remove_admin from nvme_remove 
nvme_dev_remove_admin could free dev->admin_q and the admin_tagset
while they are being accessed by nvme_dev_disable(), which can be called
by nvme_reset_work via nvme_remove_dead_ctrl.

Commit cb4bfda62a ("nvme-pci: fix hot removal during error handling")
intended to avoid requests being stuck on a removed controller by killing
the admin queue. But the later fix c8e9e9b764 ("nvme-pci: unquiesce
admin queue on shutdown"), together with nvme_dev_disable(dev, true)
right before nvme_dev_remove_admin() could help dispatch requests and
fail them early, so we don't need nvme_dev_remove_admin() any more.

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.
