Since befs_bread merely calls sb_bread, replace it by sb_bread.

This simplifies the code.
The only thing you lose is this line:
befs_debug(sb, "---> Enter %s %lu", __func__, (unsigned long)block);
Which doesn't have much use when the function doesn't exist.
All calls of befs_bread() later check if the return is NULL and write a
befs_error() if its. So you keep all error checking, which is important.
I think it is a good idea. I don't foresee new calls to befs_bread() added
that would justify its existence.
