Manivannan Sadhasivam 23bab2b8e0 bus: mhi: ep: Do not allocate event ring element on stack 
[ Upstream commit 987fdb5a43 ]

It is possible that the host controller driver would use DMA framework to
write the event ring element. So avoid allocating event ring element on the
stack as DMA cannot work on vmalloc memory.
