[PATCH 3/3] reservation: revert "wait only with non-zero timeout specified (v3)"

[Christian König]

From: Christian König <christian.koenig at amd.com>

This reverts commit fb8b7d2b9d80e1e71f379e57355936bd2b024be9.

Otherwise signaling might never be activated on the fences. This can
result in infinite waiting with hardware which has unreliable interrupts.
