vfs: get_sb_single() - do not pass options twice

Browse Source 
commit 9329d1beae upstream.

Filesystem code usually destroys the option buffer while
parsing it. This leads to errors when the same buffer is
passed twice. In case we fill a new superblock do not call
remount.

This is needed to quite a warning that the debugfs code
causes every boot.
