Bump UFS1 extended attribute max name length to 256
For extended attribute name max length, kernel filesystem-independant
which are both defined as KERNEL_NAME_MAX and fits Linux limit of 255
without training \0.
UFS1 code had a lower limit that broke Linux compatibility. We can bump
the limit without sacrifying backward compatibility, because:
1) There is no API exposing this limit outside the kernel. Upper kernel
layers have a larger limit handle the increase without a hitch
2) Each attribute has its own backing store in the fileystem, the name
of the backing store matching the attribute name. A newer kernel can
create/read/write backing store for longer attribute names and will
have no problem with existing shorter names.
