Auke Kok dc5bd99d15 Fix unlocked pt_excl in scoutfs_readahead ...

This caller of scoutfs_get_block is now actively used in el10 and
the WARN_ON_ONCE(!lock) in data.c:567 triggers. Add the
scoutfs_per_task_add_excl/del calls in scoutfs_readpage,
scoutfs_readpages, and scoutfs_readahead to register the cluster
lock for scoutfs_get_block_read.

Add unconditionally rather than guarded by the add_excl return,
since these methods can be reached reentrantly from a top-level
read that already added the entry. Skipping the I/O in that case
left BUG_ON(!list_empty(pages)) in scoutfs_readpages and the page
locked in scoutfs_readpage.

Move scoutfs_per_task_del before scoutfs_unlock to match the
ordering used by file.c read/write paths.
