Fix up format

Remove leftover portion of error message, where format string uses
an argument that no longer is passed, causing the error message to
have a random number added to it:

	Request failed: %@ (%d), got %d

The ", got %d" portion is a left-over from a previous iteration of
the message, and the value it expects is now the one provided in
the parentesis before it.
