Thomas Weißschuh 5e7d18a52c fs: avoid empty option when generating legacy mount string 
commit 62176420274db5b5127cd7a0083a9aeb461756ee upstream.

As each option string fragment is always prepended with a comma it would
happen that the whole string always starts with a comma. This could be
interpreted by filesystem drivers as an empty option and may produce
errors.

For example the NTFS driver from ntfs.ko behaves like this and fails
when mounted via the new API.
