For write, verify DIF/DIX before submission and for read, verify
DIF/DIX after successful completion.
As same as the NVMe bdev module and the NULL bdev module, DIF/DIX
verification is done based on the DIF type and DIF insert/strip is
not supported.
In near future, the bdev I/O APIs bring an I/O flag to the underlying
bdev and the malloc bdev module will be able to decide DIF/DIX
verification based on the I/O flag.
One important feature is to setup protection information when
creating a malloc disk. Otherwise, all initial reads will fail
if protection information is enabled.
For users, add some explanation about the dif_type parameter
into doc/jsonrpc.md.
