Kostiantyn Kostiuk edf3780a7d qga-vss: Write hex value of error in log
QGA-VSS writes error using error_setg_win32_internal,
which call g_win32_error_message.

g_win32_error_message - translate a Win32 error code
(as returned by GetLastError()) into the corresponding message.

In the same time, we call error_setg_win32_internal with
error codes from different Windows componets like VSS or
Performance monitor that provides different codes and
can't be converted with g_win32_error_message. In this
case, the empty suffix will be returned so error will be
masked.

This commit directly add hex value of error code.

Reproduce:
 - Run QGA command: {"execute": "guest-fsfreeze-freeze-list", "arguments": {"mountpoints": ["D:"]}}

QGA error example:
 - before changes:
  {"error": {"class": "GenericError", "desc": "failed to add D: to snapshot set: "}}
 - after changes:
  {"error": {"class": "GenericError", "desc": "failed to add D: to snapshot set: Windows error 0x8004230e: "}}
