Bart Van Assche a082f1c862 qla2x00t-32gbit: Check for MB timeout while capturing ISP27/28xx FW dump 
Add mailbox timeout checkout for ISP 27xx/28xx during FW dump procedure.
Without the timeout check, hardware lock can be held for long period. This
patch would shorten the dump procedure if a timeout condition is
encountered.

During driver unload, the remove flag will be set for all
scsi_qla_host/NPIV. This allows each NPIV to see the flag instead of
reaching for base_vha to search for it.

Bart Van Assche db78f0ff56 qla2x00t-32gbit: Add error handling for PLOGI ELS passthrough 
Add error handling logic to ELS Passthrough relating to NVME devices.
Current code does not parse error code to take proper recovery action,
instead it re-logins with the same login parameters that encountered the
error. Ex: nport handle collision.

Some storage arrays advertise FCP LUNs and NVMe namespaces behind the same

allow users to choose, on a per port basis, the kind of FC-4 type they
would like to prioritize for login.

Bart Van Assche a169500590 Makefiles: Use KBUILD_EXTRA_SYMBOLS instead of copying Module.symvers 
Copying Module.symvers is the oldest supported method for building external
kernel modules that depend on another external kernel module. Since support
for that method will be removed from Linux kernel v5.5, use
KBUILD_EXTRA_SYMBOLS instead to specify the external symbols SCST kernel
modules depend on. Support for KBUILD_EXTRA_SYMBOLS was introduced in
upstream kernel v2.6.26 so this patch drops support for kernels before
v2.6.26.
