The | grep -q 'No such file' might be useless because the error likely goes to stderr, while the pipe reads from stdout.
You need some additional file descriptor magic such as
2>&1 | grep ... (merge stderr with stdout) or
2>&1 >/dev/null | grep ...(merge stderr with stdout then suppress stdout, i.e. capture only stderr).
Further the exit status is reverse: if grep finds something (an error), the exit status is zero!
The following runs directly on the get stuff, lets grep print an error,
and adds an "okay" otherwise.
Code:
sftp $SFTP_USER@$SERVER <<EOF 2>&1 | grep 'No such file'
cd $SFTP_RDIR
get $SFTP_RFILE
bye 
EOF
if [ $? -eq 1 ]; then
  # grep did not find an error
  echo "okay"
fi

sftp-server(1M) 					  System Administration Commands					   sftp-server(1M)

NAME

       sftp-server - SFTP server subsystem

SYNOPSIS

       /usr/lib/ssh/sftp-server

DESCRIPTION

       sftp-server implements the server side of the SSH File Transfer Protocol as defined in the IETF draft-ietf-secsh-filexfer.

       sftp-server is a subsystem for sshd(1M) and must not be run directly. There are no options or config settings.

       To enable the sftp-server subsystem for sshd add the following to /etc/ssh/sshd_config:

       Subsystem   sftp     /usr/lib/ssh/sftp-server

       See sshd_config(4) for a description of the format and contents of that file.

       There is no relationship between the protocol used by sftp-server and the FTP protocol (RFC 959) provided by in.ftpd.

EXIT STATUS

       The following exit values are returned:

       0	Successful completion.

       >0	An error occurred.

FILES

       /usr/lib/sftp-server
