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.
