bpf: Add sleepable argument to bpf_alloc_pages()
bpf_alloc_pages() currently decides whether it may use the
blocking page allocator from the current execution context
alone. Let callers further restrict that choice by passing
whether their context is sleepable.
Use the blocking allocator only when both the caller and
runtime context allow sleeping. Add __GFP_RETRY_MAYFAIL so
this path can reclaim without invoking the OOM killer when
the allocation is charged to another memcg. Existing
non-sleepable callers retain the no-lock allocation behavior.
