radeonsi: fix user fence space when MCBP is enabled

Browse Source 
When MCBP is enabled, IB maybe preempted which will also update
the preempted fence field of the user fence. So we need to reserve
enough space for each user fence.

Fixes: 89d2dac554 "radeonsi: enable preemption if the kernel enabled it"
