From: Natanael Copa <ncopa@alpinelinux.org>
Fix build with musl libc by using warn(3) instead of using the GNU
specific error(3).
`error(0, errno, ...)` is identical to `warn(...)` so replace:
error(0, ret, ...);
with the identical:
errno = ret;
warn(...);
We could have used the identical `warnx("...: %s", strerror(ret))` but
strerror(3) is not thread-safe and the strerror_r variant has two
incompatible versions, one GNU specific and one XSI-compliant. Avoid the
mess by letting `warn` use the thread-local errno.
This also fixes error message for kzmalloc failures which previously
would always have given "Unknown error -1", since that is what
strerror(-1) returns. Let 'warn' use the proper error message from errno
which is set by kzalloc.

Fixes: f09ede6c8fd1 ("bus/dpaa: add BMAN driver core")
Fixes: 5b22cf744689 ("bus/dpaa: introducing FMan configurations")
