temp Fix for dsm_flag_page_remote bud: dsm_initiate_fault replaced by handle_mm_fault to avoid bug exit; Fixing missed error handling
 replaced -EEXIST by -EEFAULT to stay consistent with the error returned as the insert_mr function can either fail because of the MR already exist or a alloc fault or another error.
 changed from using handle_mm_fault to get_user_page and reduce code deduplication in order to correct the bug at bootstrap
