smb: client: fix FSCTL_GET_REPARSE_POINT against NetApp

NetApp server requires the file to be open with FILE_READ_EA access in
order to support FSCTL_GET_REPARSE_POINT, otherwise it will return
STATUS_INVALID_DEVICE_REQUEST.  It doesn't make any sense because
there's no requirement for FILE_READ_EA bit to be set nor
STATUS_INVALID_DEVICE_REQUEST being used for something other than
"unsupported reparse points" in MS-FSA.

To fix it and improve compatibility, set FILE_READ_EA & SYNCHRONIZE
bits to match what Windows client currently does.
