[PATCH AUTOSEL 5.10 09/45] scsi: ufs: Relax the condition of UFSHCI_QUIRK_SKIP_MANUAL_WB_FLUSH_CTRL

[ Upstream commit 21acf4601cc63cf564c6fc1a74d81b191313c929 ]

UFSHCI_QUIRK_SKIP_MANUAL_WB_FLUSH_CTRL is intended to skip enabling
fWriteBoosterBufferFlushEn while WriteBooster is initializing.  Therefore
it is better to apply the checking during WriteBooster initialization only.
