nand: Extend nand_(read|write)_skip_bad with *actual and limit parameters
We make these two functions take a size_t pointer to how much space
was used on NAND to read or write the buffer (when reads/writes happen)
so that bad blocks can be accounted for. We also make them take an
loff_t limit on how much data can be read or written. This means that
we can now catch the case of when writing to a partition would exceed
the partition size due to bad blocks. To do this we also need to make
check_skip_len count not just complete blocks used but partial ones as
well. All callers of nand_(read|write)_skip_bad are adjusted to call
these with the most sensible limits available.
The changes were started by Pantelis and finished by Tom.
