[PATCH iproute2-next v2] dcb: Fix compilation warning about reallocarray

[Roi Dayan <roid@nvidia.com>]

In older distros we need bsd/stdlib.h but newer distro doesn't
need it. Also old distro will need libbsd-devel installed and newer
doesn't. To remove a possible dependency on libbsd-devel replace usage
of reallocarray to realloc.

dcb_app.c: In function ‘dcb_app_table_push’:
dcb_app.c:68:25: warning: implicit declaration of function ‘reallocarray’; did you mean ‘realloc’?

Fixes: 8e9bed1493f5 ("dcb: Add a subtool for the DCB APP object")

Notes:
    v2
    - tag for iproute next
    - replace reallocarray with realloc instead of messing with libbsd
