azure: Accept variation in error msg from mount for ntfs volumes

If Azure detects an ntfs filesystem type during mount attempt, it should
still report the resource device as reformattable. There are slight
differences in error message format on RedHat and SuSE. This patch
simplifies the expected error match to work on both distributions.
