Yu Kuai fcdf582dc5 blk-wbt: fix that 'rwb->wc' is always set to 1 in wbt_init() ...

commit 285febabac upstream.

commit 8c5035dfbb ("blk-wbt: call rq_qos_add() after wb_normal is
initialized") moves wbt_set_write_cache() before rq_qos_add(), which
is wrong because wbt_rq_qos() is still NULL.

Fix the problem by removing wbt_set_write_cache() and setting 'rwb->wc'
directly. Noted that this patch also remove the redundant setting of
'rab->wc'.

Fixes: 8c5035dfbb ("blk-wbt: call rq_qos_add() after wb_normal is initialized")
