Subject: [PATCH] soc: fsl: cpm1: qmc: Fix error check for devm_ioremap_resource() in qmc_qe_init_resources()

Fix wrong variable used for error checking after devm_ioremap_resource()
call. The function checks qmc->scc_pram instead of qmc->dpram, which
could lead to incorrect error handling.

Fixes: eb680d563089 ("soc: fsl: cpm1: qmc: Add support for QUICC Engine (QE) implementation")
