features/quota: Avoid mem_put on null local
Problem: QUOTA_STACK_UNWIND does not check if local is NULL before mem_put. This leads to a callingfn log for every setxattr in quota. Fix: Made sure the mem_put happens only on non-null local in quota. Additional changes: Removed unused QUOTA_STACK_DESTROY macro. Tests: Peformed setfattr on the mount point and the Invalid argument logs don't come anymore. Checked that the change does not introduce any memory leak in quota.
