Kernel: Change Inode::{read/write}_bytes interface to KResultOr<ssize_t>

Browse source 
The error handling in all these cases was still using the old style
negative values to indicate errors. We have a nicer solution for this
now with KResultOr<T>. This change switches the interface and then all
implementers to use the new style.
