The kernel NFS mount option parser should ignore the retry= mount option
since it is meaningful only in user space. Today it expects a number
rather than arbitrary text, so it ignores the option if the value is
numeric, but chokes if there are other characters in the value.
Change it to allow any text (except ",") as its value.
