eventfs: Fix events beyond NAME_MAX blocking tasks
Eventfs uses simple_lookup(), however, it will fail if the name of the
entry is beyond NAME_MAX length. When this error is encountered, eventfs
still tries to create dentries instead of skipping the dentry creation.
When the dentry is attempted to be created in this state d_wait_lookup()
will loop forever, waiting for the lookup to be removed.
Fix eventfs to return the error in simple_lookup() back to the caller
instead of continuing to try to create the dentry.
