Subject: [PATCH v2 0/1] device-dax: avoid an unnecessary check in alloc_dev_dax_range()

v1 --> v2:
In v1, I use the "goto" statement to merge two identical __release_region() calls.
However, the new patch https://lkml.org/lkml/2020/12/18/735 deletes one of them, the
"goto" becomes worthless. So when krealloc() failed, directly call __release_region()
and return error code.
