Darren Kenny 589500ad37 fs/btrfs: Fix more fuzz issues related to chunks 
The corpus was generating issues in grub_btrfs_read_logical() when
attempting to iterate over stripe entries in the superblock's
bootmapping.

In most cases the reason for the failure was that the number of stripes
in chunk->nstripes exceeded the possible space statically allocated in
superblock bootmapping space. Each stripe entry in the bootmapping block
consists of a grub_btrfs_key followed by a grub_btrfs_chunk_stripe.

Another issue that came up was that while calculating the chunk size,
in an earlier piece of code in that function, depending on the data
provided in the btrfs file system, it would end up calculating a size
that was too small to contain even 1 grub_btrfs_chunk_item, which is
obviously invalid too.
