ASN.1: Fix check for strdup() success
commit 5a43001c01691dcbd396541e6faa2c0077378f48 upstream.
It seems there is a misprint in the check of strdup() return code that
can lead to NULL pointer dereference.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: 4520c6a49af8 ("X.509: Add simple ASN.1 grammar compiler")
