Sansa AMS bootloader: enter USB mode only when needed
- If an error happens when reading partitions / rockbox.sansa - If the select button was pressed add an argument to error() to not power off, when we're going to enter USB mode to try to fix the problem, but display the error message anyway for debugging purpose git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27075 a1c6a512-1295-4272-9138-f99709370657
