s390/dasd: fix error checks in dasd_copy_pair_store()
[ Upstream commit 8e64d2356cbc800b4cd0e3e614797f76bcf0cdb8 ]
dasd_add_busid() can return an error via ERR_PTR() if an allocation
fails. However, two callsites in dasd_copy_pair_store() do not check
the result, potentially resulting in a NULL pointer dereference. Fix
this by checking the result with IS_ERR() and returning the error up
the stack.
