Fixed a compiler issue with arm neon build.

Problem: When building webrtc in ARM but not Android:

third_party/webrtc/modules/audio_processing/ns/nsx_core_neon.c: In function 'WebRtcNsx_NoiseEstimationNeon':
third_party/webrtc/modules/audio_processing/ns/nsx_core_neon.c:248:7: note: use -flax-vector-conversions to permit conversions between vectors with differing element types or numbers of subparts

third_party/webrtc/modules/audio_processing/ns/nsx_core_neon.c:248:17: error: incompatible types when assigning to type 'int16x8_t' from type 'uint16x8_t'
