Josh Poimboeuf 9025688bf6 module: Fix device table module aliases ...

Commit 6717e8f91d ("kbuild: Remove 'kmod_' prefix from
__KBUILD_MODNAME") inadvertently broke module alias generation for
modules which rely on MODULE_DEVICE_TABLE().

It removed the "kmod_" prefix from __KBUILD_MODNAME, which caused
MODULE_DEVICE_TABLE() to generate a symbol name which no longer matched
the format expected by handle_moddevtable() in scripts/mod/file2alias.c.

As a result, modpost failed to find the device tables, leading to
missing module aliases.

Fix this by explicitly adding the "kmod_" string within the
MODULE_DEVICE_TABLE() macro itself, restoring the symbol name to the
format expected by file2alias.c.
