[PATCH v3 0/9] Coverity fixes for EAL memory

[Anatoly Burakov <anatoly.burakov@intel.com>]

This patchset fixes a host of coverity issues in memory subsystem
introduced with recent DPDK memory hotplug patchset.

Coverity issues fixed:
- 272601 - leaking fd
- 272560 - double close fd
- 272568 - leaking fd
- 272570 - leaking fd
- 272589 - dereference before null check
- 272602 - freeing wrong pointer
- 272608 - expression does nothing
- 272584 - use after free

Coverity issues not fixed:
- 272577 - negative return not handled
- 272578 - negative return not handled
  - Proper usage of API guarantees no negative returns

Additionally, also replace all instances of snprintf with strlcpy.

v3:
- Drop fixes for 272577 and 272578 and mark them as false positives

v2:
- Rebase on top of latest master
