RDMA/uverbs: select CONFIG_DMA_SHARED_BUFFER 



The addition of dmabuf support in uverbs means that it is no
longer possible to build infiniband support if that is disabled:

arm-linux-gnueabi-ld: drivers/infiniband/core/ib_core_uverbs.o: in function `rdma_user_mmap_entry_remove.part.0':
ib_core_uverbs.c:(.text+0x508): undefined reference to `dma_buf_move_notify'
(dma_buf_move_notify): Unknown destination type (ARM/Thumb) in drivers/infiniband/core/ib_core_uverbs.o
ib_core_uverbs.c:(.text+0x518): undefined reference to `dma_resv_wait_timeout'
(dma_resv_wait_timeout): Unknown destination type (ARM/Thumb) in drivers/infiniband/core/ib_core_uverbs.o

Select this from Kconfig, as we do for the other users.
