Amir Mohammad Jahangirzad 62b4f6c6ab fs/orangefs: use snprintf() instead of sprintf()
[ Upstream commit cdfa130465 ]

sprintf() is discouraged for use with bounded destination buffers
as it does not prevent buffer overflows when the formatted output
exceeds the destination buffer size. snprintf() is a safer
alternative as it limits the number of bytes written and ensures
NUL-termination.

Replace sprintf() with snprintf() for copying the debug string
into a temporary buffer, using ORANGEFS_MAX_DEBUG_STRING_LEN as
the maximum size to ensure safe formatting and prevent memory
corruption in edge cases.

EDIT: After this patch sat on linux-next for a few days, Dan
Carpenter saw it and suggested that I use scnprintf instead of
snprintf. I made the change and retested.
