[PATCH v4 3/4] mldev: fix minsize build

[Thomas Monjalon <thomas@monjalon.net>]

This error is seen in build of type "minsize":

In function 'rte_ml_dev_pmd_allocate':
lib/mldev/rte_mldev.c:84:16: error:
'dev' may be used uninitialized [-Werror=maybe-uninitialized]
   84 |         if (dev->data == NULL) {
      |             ~~~^~~~~~

It looks to be a compiler issue because we are not supposed
to reach this point without finding a device to assign.

The variable is initialized to allow compiling with "minsize" option.
