ufs/extattr.h: Fix documentation of ea_name termination

The ea_name string is not nul-terminated.  Correct the documentation.

Because the subsequent field is padded to 8 bytes, and the padding is
zeroed, the ea_name string will appear to be nul-terminated whenever the
length isn't exactly one (mod eight).

This was introduced in r167010 (2007).

Additionally, mark the length fields as unsigned.  This particularly
matters for the single byte ea_namelength field, which can represent
extended attribute names up to 255 bytes long.

No functional change.
