The result from a call of the function “devm_kasprintf” was passed to
a subsequent function call without checking for a null pointer before
(according to a memory allocation failure).
This issue was detected by using the Coccinelle software.
Thus return directly after a failed devm_kasprintf() call.
Fixes: 724142f8c42a7 ("fpga: dfl: fme: add performance reporting support")
