The only motivation for using -EAGAIN in commit 0542ad88fbdd81bb ("firmware loader: Fix _request_firmware_load() return val for fw load abort") was to distinguish the error from -ENOMEM, and so there is no real reason in keeping it. -EAGAIN is typically used to tell the userspace to try something again and in this case re-using the sysfs loading interface cannot be retried when a timeout happens, so the return value is also bogus. -ETIMEDOUT is received when the wait times out and returning that is much more telling of what the reason for the failure was. So, just propagate that instead of returning -EAGAIN.
