A recent commit removed errno.h from rte_common.h.
It has to be added in various places where it is used,
and was implicitly included via rte_common.h,
but was forgotten in gpu/cuda.
As a result, the compilation is broken:
drivers/gpu/cuda/gdrcopy.c:116:17: error: ‘ENOTSUP’ undeclared
Note that rte_errno.h does not include errno.h.
The include of errno.h is added.
Fixes: 72b452c5f2 ("eal: remove unneeded includes from a public header")
