storage/posix: Fix excessive logging in WRITE fop path
I was running some write-intensive tests on my volume, and in a matter of 2 hrs, the 50GB space in my root partition was exhausted. On inspecting further, figured that excessive logging in bricks was the cause - specifically in posix write when posix_check_internal_writes() does dict_get() without a NULL-check on xdata. Change-Id: I89de57a3a90ca5c375e5b9477801a9e5ff018bbf fixes: bz#1590655 Signed-off-by: Krutika Dhananjay <kdhananj@redhat.com>
