[linux-cifs-client] patch to mount.cifs to allow it to handle USER env variable

[Steve French]

Although the USER env variable is usually set to the same thing as
getuid returns, the user may want to override it (and mount.cifs man
page, like smbfs, says it is supposed to honor the ENV variable $USER.
 Patch follows to fix that:
