remoteproc: k3: Fix NULL vs IS_ERR() bug in k3_reserved_mem_init()

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

Fixes: 67a7bc7f03 ("remoteproc: Use of_reserved_mem_region_* functions for "memory-region"")
