gfapi: Duplicate the buffer sent in setxattr calls
Issue:
The caller of glfs_setxattr sends a buffer to set as the value.
We create a dict in which the pointer to the value is set.
Underlying layers like md-cache take a ref on this dict to store
the value for a longer time. But the moment setxattr is complete,
the caller of glfs_setxattr can free the value memory.
Solution:
memcpy the setxattr value to the gluster buffer.
