Subject: [PATCH 5.15 083/279] f2fs: fix to use WHINT_MODE

From: Keoseong Park <keosung.park@...sung.com>

[ Upstream commit 011e0868e0cf1237675b22e36fffa958fb08f46e ]

Since active_logs can be set to 2 or 4 or NR_CURSEG_PERSIST_TYPE(6),
it cannot be set to NR_CURSEG_TYPE(8).
That is, whint_mode is always off.

Therefore, the condition is changed from NR_CURSEG_TYPE to NR_CURSEG_PERSIST_TYPE.
