btrfs-progs: kernel-shared: update const of parameters accessors.h
Sync up with kernel and fix warnings reported by -Wcast-qual. eg. Most of the change is due to extent_buffer::data, which is a direct struct member, unlike in kernel where it's an array of pages. The const qualifier cannot be used the same way so it's dropped in affected herlpers. Signed-off-by: David Sterba <dsterba@suse.com>
