[SCSI] fc_transport: fix sysfs deadlock on vport delete
When the vport attribute "delete" is used to delete the vport, sysfs
deadlocks waiting for the write to complete, which is waiting for the
sysfs teardown to complete. Moved this effort to a work_q element.
Took the opportunity to make some other cosmetic changes:
- removed tabs in Doc file - replaced with expanded spaces
- minor copyright text and author text updates
- removed a bunch of trailing whitespace
