NFSD: Fix destination buffer size in nfsd4_ssc_setup_dul()
Commit 5304877936c0 ("NFSD: Fix strncpy() fortify warning") replaced
strncpy(,, sizeof(..)) with strlcpy(,, sizeof(..) - 1), but strlcpy()
already guaranteed NUL-termination of the destination buffer and
subtracting one byte potentially truncated the source string.
The incorrect size was then carried over in commit 72f78ae00a8e ("NFSD:
move from strlcpy with unused retval to strscpy") when switching from
strlcpy() to strscpy().
Fix this off-by-one error by using the full size of the destination
buffer again.
