Revert "microblaze_mmu_v2: Update signal returning address"

This reverts commit 8b28626. Offset -8 is wrong because when it is applied then one instruction before brki r14, 8 is called again when we return. Offset -4 is correct and brki instruction is called again. This change came from ancient MMU kernel. Signed-off-by: Michal Simek <[email protected]>
