Fixed a crash issue in NSX module.

Run time error message for function WebRtcNsx_PrepareSpectrumNeon():  "Bad access at:  0x4f535c:  vst1.16{d16, d17, d18, d19}, [r2], r12"

Cause: "anaLen" was defined as int16_t and should have been read as such in assembly function WebRtcNsx_PrepareSpectrumNeon().

Fix: Changed anaLen's definition to int in the header file instead.
