[PATCH] Byteorder fix for read-tree, new -m semantics version.

[PATCH] Byteorder fix for read-tree, new -m semantics version.

The ce_namelen field has been renamed to ce_flags and split into
the top 2-bit unused, next 2-bit stage number and the lowest
12-bit name-length, stored in the network byte order.  A new
macro create_ce_flags() is defined to synthesize this value from
length and stage, but it forgets to turn the value into the
network byte order.  Here is a fix.
