[OpenWrt-Devel] [PATCH] scripts/getver.sh: silence rev-list errors

[Petr Štetiar]

Shallow copies are quite common on CI platforms nowadays, making REBOOT
tag unavailable, thus producing following confusing errors in the build
logs:

 fatal: Invalid revision range ee53a240ac902dc83209008a2671e7fdcf55957a..HEAD
 fatal: Invalid revision range ee53a240ac902dc83209008a2671e7fdcf55957a..0493d57e04774d47921a7d2014b567455d5dc16b
