readdir-ahead: Enhance EOD detection logic
Issue:
Currently end of directory is identified on obtaining a
readdirp_cbk with op_ret = 0 (i.e. 0 entries fetched in
readdirp). Thus an extra readdirp is required for every
directory just to identify EOD. Consider a case of listing
large number of small directories. The readdirp fops required
are doubled in that case.
Solution:
On reaching the EOD, posix sets the op_errno to ENOENT,
hence along with looking for 'op_ret == 0' we also
look for 'operrno == ENOENT' ehile checking for EOD condition
