c5ff6adeae Fix unloading of scst_vdisk while I/O is ongoing 
Call scst_free_device() directly instead of when the final dev->refcnt
put happens. Call scst_assign_dev_handler(dev, &scst_null_devtype) after
processing of I/O commands for 'dev' has finished. Hold the RCU read lock
while invoking percpu_ref_get(&dev->refcnt) in the LUN translation code.
This patch fixes the following crash when scst_vdisk is unloaded while I/O
is ongoing:

bb43fbc468 scst/src/Makefile: Run /usr/sbin/weak-modules --remove-kernel before install 
Apparently RHEL 8 / CentOS 8 create soft links in the weak-modules to SCST
directory but do not update these links correctly after having upgraded to
a newer kernel version and after having reinstalled SCST. Hence remove all
weak module links before installing SCST.

3a957d352a qla2xxx: Do not log message when reading port speed via sysfs 
Calling ql_log() inside qla2x00_port_speed_show() is causing messages to be
output to the console for no particularly good reason.  The sysfs read
routine should just return the information to userspace.  The only reason
to log a message is when the port speed actually changes, and this already
occurs elsewhere.

6bbee1b222 qla2xxx: Fix hang when issuing nvme disconnect-all in NPIV 
In NPIV environment, a NPIV host may use a queue pair created by base host
or other NPIVs, so the check for a queue pair created by this NPIV is not
correct, and can cause an abort to fail, which in turn means the NVME
command not returned.  This leads to hang in nvme_fc layer in
nvme_fc_delete_association() which waits for all I/Os to be returned, which
is seen as hang in the application.
