[PATCH] mm/hugetlb: change ENOSPC to ENOMEM in alloc_hugetlb_folio

[Dafna Hirschfeld <dafna.hirschfeld@intel.com>]

The error ENOSPC is translated in vmf_error to VM_FAULT_SIGBUS which is
further translated in EFAULT in i.e. pin/get_user_pages.
But when running out of pages/hugepages we expect to see ENOMEM and
not EFAULT.
