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: "}}
