cifs: open_cached_dir(): add FILE_READ_EA to desired access

[ Upstream commit f1b8224b4e6ed59e7e6f5c548673c67410098d8d ]

Since smb2_query_eas() reads EA and uses cached directory,
open_cached_dir() should request FILE_READ_EA access.

Otherwise listxattr() and getxattr() will fail with EACCES
(0xc0000022 STATUS_ACCESS_DENIED SMB status).
