Stefan Richter 0238507b95 firewire: core: document fw_csr_string's truncation of long strings ...

fw_csr_string() truncates and terminates target strings like strlcpy()
does.  Unlike strlcpy(), it returns the target strlen, not the source
strlen, hence users of fw_csr_string() are unable to detect truncation.

Point this behavior out in the kerneldoc comment.
