Subject: features/shard: Use fd lookup post file open

Issue:
When a process has the open fd and the same file is
unlinked in middle of the operations, then file based
lookup fails with ENOENT or stale file

Solution:
When the file already open and fd is available, use fstat
to get the file attributes

Fixes: #1281
