spi: fsl-qspi: Fix double cleanup in probe error path
commit 5d07ab2a7fa1305e429d9221716582f290b58078 upstream.
Commit 40369bfe717e ("spi: fsl-qspi: use devm function instead of driver
remove") introduced managed cleanup via fsl_qspi_cleanup(), but
incorrectly retain manual cleanup in two scenarios:
- On devm_add_action_or_reset() failure, the function automatically call
fsl_qspi_cleanup(). However, the current code still jumps to
err_destroy_mutex, repeating cleanup.
- After the fsl_qspi_cleanup() action is added successfully, there is no
need to manually perform the cleanup in the subsequent error path.
However, the current code still jumps to err_destroy_mutex on spi
controller failure, repeating cleanup.
Skip redundant manual cleanup calls to fix these issues.
