Bart Van Assche 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:

BUG: unable to handle kernel NULL pointer dereference at 0000000000000368

Bart Van Assche 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.

Bart Van Assche 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.
