remoteproc: qcom_q6v5_adsp: Fix a NULL vs IS_ERR() check in adsp_alloc_memory_region()

Browse Source 
The devm_ioremap_resource_wc() function never returns NULL, it returns
error pointers.  Update the check to match.

Fixes: c70b9d5fdc ("remoteproc: qcom: Use of_reserved_mem_region_* functions for "memory-region"")
