In drivers/md/bcache/Kconfig, setting BCACHE_NVM_PAGES to "selected"
LIBNVDIMM and DAX is improper. This patch changes to Kconfig dependance
from "selected" to "depends on" for LIBNVDIMM and DAX.

Currently when ns fails to be allocated the error return path returns
an uninitialized return code in variable 'err'. Fix this by setting
err to -ENOMEM.
