Dan Carpenter 6294be372c md-cluster: Fix potential error pointer dereference in resize_bitmaps() 
[ Upstream commit e8abe1de43dac658dacbd04a4543e0c988a8d386 ]

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: afd756286083 ("md-cluster/raid10: resize all the bitmaps before start reshape")
