xprtrdma: Don't require LOCAL_DMA_LKEY support for fastreg
There is no need to require LOCAL_DMA_LKEY support as the
PD allocation makes sure that there is a local_dma_lkey. Also
correctly set a return value in error path.
This caused a NULL pointer dereference in mlx5 which removed
the support for LOCAL_DMA_LKEY.
Fixes: bb6c96d72879 ("xprtrdma: Replace global lkey with lkey local to PD")
