Dan Carpenter 0b702cd414 md-cluster: Fix potential error pointer dereference in resize_bitmaps() 
[ Upstream commit e8abe1de43 ]

The error handling calls md_bitmap_free(bitmap) which checks for NULL
but will Oops if we pass an error pointer.  Let's set "bitmap" to NULL
on this error path.

Fixes: afd7562860 ("md-cluster/raid10: resize all the bitmaps before start reshape")
