Dan Carpenter 2418da0204 test_firmware: Use correct snprintf() limit 
commit bd17cc5a20 upstream.

The limit here is supposed to be how much of the page is left, but it's
just using PAGE_SIZE as the limit.

The other thing to remember is that snprintf() returns the number of
bytes which would have been copied if we had had enough room.  So that
means that if we run out of space then this code would end up passing a
negative value as the limit and the kernel would print an error message.
I have change the code to use scnprintf() which returns the number of
bytes that were successfully printed (not counting the NUL terminator).

Fixes: c92316bf8e ("test_firmware: add batched firmware tests")
