[PATCH] soc: fsl: cpm1: qmc: Set the ret error code on platform_get_irq() failure

[Herve Codina]

A kernel test robot detected a missing error code:
   qmc.c:1942 qmc_probe() warn: missing error code 'ret'

Indeed, the error returned by platform_get_irq() is checked and the
operation is aborted in case of failure but the ret error code is
not set in that case.

Set the ret error code.
