scsi: target: use scoped_with_init_fs() for ALUA metadata
core_alua_write_tpg_metadata() can be called from both kthread and user
process context. Use scoped_with_init_fs() to temporarily override
current->fs for the filp_open() call when running in kthread context so
the path lookup happens in init's filesystem context.
core_alua_write_tpg_metadata() ← core_alua_update_tpg_primary_metadata()
← core_alua_do_transition_tg_pt() ← target_queued_submit_work() ←
kworker (target submission workqueue)
Also reached synchronously from configfs (user process) via the
alua_access_state and alua_tg_pt_offline attributes:
core_alua_write_tpg_metadata() ← core_alua_update_tpg_primary_metadata()
← core_alua_do_transition_tg_pt() ← core_alua_do_port_transition() ←
target_tg_pt_gp_alua_access_state_store()
In that case current->fs must not be overridden as the path should
resolve against the calling process's filesystem root.
