Yi Kuo 9900b9fee5 smb: smbdirect: fix MR registration for coalesced SG lists ... ib_dma_map_sg() modifies the provided scatterlist and returns the number of mapped entries, which can be fewer than the requested mr->sgt.nents if the DMA controller coalesces contiguous memory segments. Passing the original, uncoalesced count to ib_map_mr_sg() causes memory registration failures if coalescing actually occurs. Capture the actual mapped count returned by ib_dma_map_sg() and pass it to ib_map_mr_sg() to ensure correct MR registration. Also update the ib_dma_map_sg() error logging to drop the error pointer formatting, since the return value is an integer count rather than an error code. Ensure a proper error code (-EIO) is assigned when DMA mapping or MR registration fails.
