pci: Fix silent truncation of pcie_aer_inject_error argument
PCI AER error status is 32 bit. The HMP command supports both
symbolic and numeric error status: anything that isn't a known
symbolic value is parsed as number with strtol(). Issues:
* Empty argument yields value zero.
* Range errors from strtol() are ignored, value is UINT32_MAX.
* Values not representable in uint32_t are silently truncated.
Fix to reject such input by switching to strtoui().
