zram: permit reclaim in zstd custom allocator
When configured with pre-trained compression/decompression dictionary
support, zstd requires custom memory allocator, which it calls internally
from compression()/decompression() routines. That means allocation from
atomic context (either under entry spin-lock, or per-CPU local-lock or
both). Now, with non-atomic zram read()/write(), those limitations are
relaxed and we can allow direct and indirect reclaim.
