Martin Wilck e169980193 scsi: scsi_transport_srp: Don't block target in SRP_PORT_LOST state 
[ Upstream commit 5cd0f6f57639c5afbb36100c69281fee82c95ee7 ]

rport_dev_loss_timedout() sets the rport state to SRP_PORT_LOST and the
SCSI target state to SDEV_TRANSPORT_OFFLINE. If this races with
srp_reconnect_work(), a warning is printed:

Mar 27 18:48:07 ictm1604s01h4 kernel: dev_loss_tmo expired for SRP port-18:1 / host18.

Mar 27 18:48:07 ictm1604s01h4 kernel:  srp_reconnect_work+0x40/0xc0 [scsi_transport_srp]

Avoid this by not trying to block targets for rports in SRP_PORT_LOST
state.

README 

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.
