patch 8 for dazukofs release 3.0.0

Bug description:
If the underlaying filesystem does not implement one or more of the 
inode operations
related to extended attributes(i.e. vfat), dazukofs returns an ENOSYS 
error code. This
seems not to be the proper return value, since it results in ugly 
"function not implemented"
messages on some systems, that use extended attributes related system 
calls (this happens for example
on OpenSuse11.1 systems, every time that an "ls -l" command is executed 
within an dazukofs
that is mounted over vfat).
The  error code set by the vfs layer is indeed -EOPNOTSUPP, if those 
functions are not implemented.
So this patch replaces the ENOSYS with  EOPNOTSUPP error codes to be 
conform to the
vfs behavior.
