x86/pmem: Check for platform_device_alloc() retval

Browse source

Add proper error handling for the case when platform_device_alloc() returns
NULL due to memory allocation failure. This prevents a potential NULL pointer
dereference when trying to use the pdev pointer without checking if allocation
succeeded.
