PATCH: remove dead code flagged by coverity

[Oliver Kiddle <okiddle@xxxxxxxxxxx>]

Coverity correctly flags these two lines of code as being dead. This was
added in 42332. Unless the intention was instead for zstrtoul_underscore() to
also handle base#number syntax then this can go because it only looks
for binary, octal, decimal and hex.
