Possible null pointer dereference in logging

[apach301]

Hi,

I found some possible null pointer dereferences with Svace static analyzer.

1. Possible dereference of NULL cache_provider in xnn_create_weights_cache_with_size(): https://github.com/google/XNNPACK/blob/f9bc6b49145d6b68cc81fab1a5cb553b6d3b134b/src/runtime.c#L164-L167

Bailing out occured with uninitialized cache_provider: https://github.com/google/XNNPACK/blob/f9bc6b49145d6b68cc81fab1a5cb553b6d3b134b/src/runtime.c#L131-L143

2. Possible dereference of NULL resize_op in create_resize_bilinear2d_nhwc() during error logging: https://github.com/google/XNNPACK/blob/f9bc6b49145d6b68cc81fab1a5cb553b6d3b134b/src/operators/resize-bilinear-nhwc.c#L36-L60
