smb: client: fix query_info() replay double-free

Browse source

A response-bearing attempt can return a replayable error and free its
response buffer. If SMB2_query_info_init() fails before the next send,
cleanup retains the previous buffer type and frees that response again.

Reset response bookkeeping before each attempt to prevent the stale free.

Fixes: 4f1fffa237 ("cifs: commands that are retried should have replay flag set")
