Ezequiel García 35bfb7949b mtd: nand: Drop mtd.owner requirement in nand_scan ...

commit 20c07a5bf0 upstream.

Since commit 807f16d4db ("mtd: core: set some defaults
when dev.parent is set"), it's now legal for drivers
to call nand_scan and nand_scan_ident without setting
mtd.owner.

Drop the check and while at it remove the BUG() abuse.

[Brian: editorial note - while commit 807f16d4db wasn't explicitly
    broken, some follow-up commits in the v4.4 release broke a few
    drivers, since they would hit this BUG() if they used nand_scan()
    and were built as modules]
