staging: comedi: jr3_pci: re-work firmware copyright display

Browse source

If debug messages are enabled, the card initialization done in
`jr3_pci_auto_attach()` spits out 24 (0x18) debug messages to show the
null-terminated copyright string embedded in the firmware, one character
at a time, including the ASCII NUL characters at the end.  Factor out
the copyright display into a new function `jr3_pci_show_copyright()` and
re-work it to copy the whole copyright string into a buffer, so that it
can be shown with a single debug message.

Incidentally, this also removes a checkpatch warning "Avoid multiple
line dereference" in the original code.
