Subject: [PATCH] devargs: reset driver name pointer on parsing failure

[ upstream commit 3cdfdf2a3303bb50d98c4f1689fc4b3745ea1e4f ]

The pointer set by strdup() needs to be cleared on failure to avoid a
potential double-free from the caller.

Found with clang static analysis:
lib/librte_eal/common/eal_common_devargs.c:123:2:
warning: Attempt to free released memory
        free(buf);
        ^~~~~~~~~

Fixes: 0fe11ec592b2 ("eal: add vdev init and uninit")
