mem: fix leak after mapping failure

Patch fixes resource leak in rte_eal_hugepage_attach() where mapped files
were not freed back to the OS in case of failure. Patch uses the behavior
of Linux munmap: "It is not an error if the indicated range does not
contain any mapped pages".

Coverity issue: 13295, 13296, 13303

Fixes: af75078fece3 ("first public release")
