dma-buf: Move dma_buf_mmap() to dynamic locking specification

Browse source

Move dma_buf_mmap() function to the dynamic locking specification by
taking the reservation lock. Neither of the today's drivers take the
reservation lock within the mmap() callback, hence it's safe to enforce
the locking.
