staging: lustre: statahead: small fixes and cleanup
small fixes:
* when 'unplug' is set for ll_statahead(), sa_put() shouldn't kill
the entry found, because its inflight RPC may not finish yet.
* remove 'sai_generation', add 'lli_sa_generation' because the
former one is not safe to access without lock.
* revalidate_statahead_dentry() may fail to wait for statahead
entry to become ready, in this case it should not release this
entry, because it may be used by inflight statahead RPC.
cleanups:
* rename ll_statahead_enter() to ll_statahead().
* move dentry 'lld_sa_generation' update to ll_statahead() to
simplify code and logic.
* other small cleanups.
