Trivial cleanup for XArray.

No functional change.

Wei Yang (9):
XArray: fix comment on Zero/Retry entry
XArray: simplify the calculation of shift
XArray: handle a NULL head by itself
XArray: don't expect to have more nr_values than count
XArray: entry in last level is not expected to be a node
XArray: internal node is a xa_node when it is bigger than
XA_ZERO_ENTRY
XArray: the NULL xa_node condition is handled in xas_top
XArray: take xas_error() handling for clearer logic
XArray: adjust xa_offset till it gets the correct node
