[dpdk-dev] [PATCH 19.08 2/3] kernel/linux: reduce unneeded indents in meson build file

[Bruce Richardson <bruce.richardson@intel.com>]

Since meson 0.46, meson has supported the subdir_done() function, which
allows us to abort processing of a file early. Using this we can reduce the
indentation in our files by eliminating unnecessary else blocks.

Note: though the diff here seems fairly big, a lot of it is whitespace
change due to reduced indentation. Using "git diff -w" is recommended for
easier review.
