Alberto Faria bf5b16fa40 block: Make blk_{pread,pwrite}() return 0 on success ...

They currently return the value of their 'bytes' parameter on success.

Make them return 0 instead, for consistency with other I/O functions and
in preparation to implement them using generated_co_wrapper. This also
makes it clear that short reads/writes are not possible.
