[SCSI] zfcp: Only issue one test link command per port

When the FCP channel returns a series of commands with the error
status "test link", zfcp will send a series of ELS ADISC commands.
This is technically no problem, but it is enough to only issue one
test command per remote port. So, track whether a ELS ADISC command is
already pending, and do not send a new one if there is already a
pending command.
