Subject: [PATCH 52/69] mdadm: pass struct context for external reshapes
This patch alters mutiple functions calls so the context is passed to
external reshape functions.
There are two main reasons behind it:
- reduces number of arguments passed and unifies them,
- imsm code will make use of context in incoming patches.
