LU-11418 llog: refresh remote llog upon -ESTALE

If a distributed transaction is aborted, it will invalidate all
objects involved, which include remote catalog and update logs.

So llog_cat_declare_add_rec() will refresh remote llog upon -ESTALE,
but it only does this for chd_current_log, not chd_next_log.

If an aborted transaction happens to invalidate catalog only, and
leave chd_current_log valid, which will cause subsequent operations
fail to create chd_next_log.

This patch prepares both current and next log of catalog before
declare_write in llog_cat_declare_add_rec().

Add sanity.sh 60g.
