Subject: [PATCH] riscv: qspinlock: Fixup _Q_PENDING_LOOPS definition

From: Guo Ren <guoren@...ux.alibaba.com>

When CONFIG_RISCV_QUEUED_SPINLOCKS=y, the _Q_PENDING_LOOPS
definition is missing. Add the _Q_PENDING_LOOPS definition for
pure qspinlock usage.

Fixes: ab83647fadae ("riscv: Add qspinlock support")
