spi: fsl-qspi: Fix double cleanup in probe error path
[ Upstream commit 5d07ab2a7fa1305e429d9221716582f290b58078 ] 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.
