fuse_lowlevel: Simplify se->buf_reallocable

se->buf_reallocable is true when reading /dev/fuse is handled
from internal functions - we can set the variable in
fuse_session_receive_buf_internal(). With that we also
don't need to have it an _Atomic variable anymore.

In _fuse_session_receive_buf() we can use "bool internal"
to check if the buffer can be re-allocated.
