[PATCH 5.19 265/717] spi: cadence-quadspi: Fix PM disable depth imbalance in cqspi_probe

From: Zhang Qilong <zhangqilong3@huawei.com>

[ Upstream commit 4d0ef0a1c35189a6e8377d8ee8310ea5ef22c5f3 ]

The pm_runtime_enable will increase power disable depth. Thus
a pairing decrement is needed on the error handling path to
keep it balanced according to context.

Fixes:73d5fe0462702 ("spi: cadence-quadspi: Remove spi_master_put() in probe failure path")
