drm/amdgpu/gfx9.4.3: Fix MEC rollback loop in EOP IRQ setup
Fix the error cleanup path in gfx_v9_4_3_set_userq_eop_interrupts() by
using the correct loop condition. This ensures all previously enabled
EOP IRQs are released if setup fails.
Fixes: 832f0aa050ff ("drm/amdgpu/gfx9.4.3: add support for disabling kernel queues")
