LU-10155 recovery: support setstripe replay

Regular file open will always reserve space for LOV ea, which is used
to store user specified lov_user_md, or lov_mds_md for replay, but if
this open is the first open in 'lfs setstripe', it doesn't have
lov_user_md specified, or lov_mds_md for replay because
O_LOV_DELAY_CREATE is set, but MDT will treat the EA field in the
request as valid one, so fails in magic check in this open replay.

This patch fixes this issues on both sides:
1. client doesn't reserve space for LOV ea in
   open(O_LOV_DELAY_CREATE), this change is not necessary, but to
   make clean of the code.
2. server doesn't create OST objects for open(O_LOV_DELAY_CREATE)
   replay.

Add setstripe/setdirstripe replay test in replay-single.sh, which
are 2c, 2d.
