Btrfs: move alloc_profile_is_valid() to volumes.c

Header file is not a good place to define functions. This also moves a call to alloc_profile_is_valid() down the stack and removes a redundant check from __btrfs_alloc_chunk() - alloc_profile_is_valid() takes it into account. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
