Various functions/macros assume valid alignment for casting. Compiling
an application against it with -Werror and -Wcast-align may trigger
cast-align warnings.
To avoid those, add first (void *) castings.

Note: for eal/arm64 similar changes could be applied to
lib/eal/arm/include/rte_memcpy_64.h. I do not have a system in which I
encounter such warnings, so currently I do not post any change for it.

  net: avoid cast-align warning in VLAN insert function
  mbuf: avoid cast-align warning in pktmbuf mtod offset macro
  eal/x86: avoid cast-align warning in x86 memcpy functions
