EA bug while convert from INLINE to EXTENT with XATTR_REPLACE

["Tang Lingbo (Allan)" <atang@xxxxxxxxxxxxxxxxxxxx>]

Hi,

One of the attached files is used to hit the bug as following, the patch is
my solution:

A. set a EA with 10 chars (name length + value length) 
B. change above name's value with chars more than 32 

If we used the EA through lib, the operations seems OK because it
has never used XATTR_REPLACE flag.

The patch will solve the problem.

Regards,
Allan
