[PATCH v2 3/4] mm: vmscan: drop unused gfp_mask parameter from __node_reclaim()

[Ridong Chen <ridong.chen@linux.dev>]

From: Ridong Chen <chenridong@xiaomi.com>

Commit 57972c78e678 ("mm/vmscan: make __node_reclaim() more generic")
moved the scan_control construction out to the callers and passed the
struct in by pointer.  After that change every use of the gfp mask inside
__node_reclaim() goes through sc->gfp_mask, leaving the gfp_mask parameter
unused. Just remove the dead parameter and update the callers accordingly.
No functional change.
