[PATCH] spi: cadence-qspi: Fix runtime PM imbalance in probe

[Ali Tariq <alitariq45892@gmail.com>]

The probe function incorrectly calls pm_runtime_put_autosuspend()
twice in succession at the end of successful probe, dropping two
runtime PM references while only one was acquired earlier with
pm_runtime_get_sync(). This causes a usage count underflow:

    cadence-qspi 13010000.spi: Runtime PM usage count underflow!

Remove the first redundant pm_runtime_put_autosuspend() call to
balance the reference count.

Tested on StarFive VisionFive 2 v1.2A board.

Fixes: 30dbc1c8d50f ("spi: cadence-qspi: defer runtime support on socfpga if reset bit is enabled")
