jfs: xattr: fix buffer overflow for invalid xattr

In the Linux kernel, the following vulnerability has been resolved:

jfs: xattr: fix buffer overflow for invalid xattr

When an xattr size is not what is expected, it is printed out to the
kernel log in hex format as a form of debugging.  But when that xattr
size is bigger than the expected size, printing it out can cause an
access off the end of the buffer.

Fix this all up by properly restricting the size of the debug hex dump
in the kernel log.

CWE-120 Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer.

CWE-121 Stack-based Buffer Overflow

A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
