dma-buf/drivers: make reserving a shared slot mandatory v4
Audit all the users of dma_resv_add_excl_fence() and make sure they
reserve a shared slot also when only trying to add an exclusive fence.
This is the next step towards handling the exclusive fence like a
shared one.
v2: fix missed case in amdgpu
v3: and two more radeon, rename function
v4: add one more case to TTM, fix i915 after rebase
