Btrfs: fix error handling in map_private_extent_buffer
map_private_extent_buffer() can return -EINVAL in two different cases,
1. when the requested contents span two pages if nodesize is larger
than pagesize,
2. when it detects something insane.
The 2nd one used to be only a WARN_ON(1), and we decided to return a error
to callers, but we didn't fix up all its callers, which will be
addressed by this patch.
Without this, btrfs may end up with 'general protection', ie.
reading invalid memory.
