Subject: [PATCH] Linux 5.0 compat: ASM_BUG macro

The 5.0 kernel defines the macro ASM_BUG.  In order to prevent a
conflict and build failure rename ASM_BUG to ZFS_ASM_BUG.  This
is currently only an issue on aarch64 but all instances of
ASM_BUG we're renamed to avoid any future conflict on x86_64.
