Bug 1044344

Description of problem:
Assertion failure is seen from marker.quota after setting quota on a directory and creating file in that directory and running fgetattr from the brick on that file.Also seen ia_gfid is null on a lookup when file create command was issued.

Version-Release number of selected component (if applicable):
glusterfs-fuse-3.4.0.49rhs-1.el6rhs.x86_64
glusterfs-server-3.4.0.49rhs-1.el6rhs.x86_64
samba-glusterfs-3.6.9-167.3.el6rhs.x86_64

glusterfs-api-devel-3.4.0.49rhs-1.el6rhs.x86_64
glusterfs-rdma-3.4.0.49rhs-1.el6rhs.x86_64

glusterfs-api-3.4.0.49rhs-1.el6rhs.x86_64
glusterfs-devel-3.4.0.49rhs-1.el6rhs.x86_64


How reproducible:
Tried once.

Steps to Reproduce:
1. smb mount a volume, create a directory on mount point.
2. set quota limit to 2 GB for the directory.
3. Run I/O from mount point.Create files.
4. Run fgetattr from brick on the file newly created.

Actual results:
Assertion failure from marker.quota is observed in log messages. 

Expected results:
No assertion failure should be seen.
