[PATCH] block: follow links before check if cdev_is_block_partition

[Marco Felsch]

cdev_is_block_partition() fails if a cdev is passed which is a
parition-link. Most of our barebox code is link-aware by resolving the
links first.

Make it more user-friendly and resolve the possible cdev parttion link
first before performing the actual check.
