Fix SMB STATUS_ACCESS_DENIED on rename after read 

smbclient.open_file() opens files with default share mode (read-only),
which blocks subsequent rename/delete operations because the underlying
SMB connection stays in the library's connection pool.

Use share_access="rwd" to allow concurrent read/write/delete, making
the move-after-read operation deterministically work.
