CRAS: linear_resampler - Fix resample frames calculation Originally the in/out frames calculation is not accurate enough, that it always result a number sightly larger then the actual number of converted frames, which could cause problem in the usage of chained SRC. Add into account the offset state of the linear resampler, so the in <-> out frames calculation aligns with the exact converted frame numbers of the next call to linear_resampler_resample(). BUG=chromium:460515 TEST=Apply whole patch set, open flash video(44.1KHz, 2048 fr) and a web audio demo page(48KHz, 1024 fr) with two Jabra speakerphones enabled. Verify audio does not stop when play for an hour long.

CRAS: linear_resampler - Fix corner cases In linear_resampler_resample function, if dst_frames is zero then it's incorrect to iterate dst_idx from zero and it will leak one frames in the source buffer. If src_frames points to an unsigned of value 0, we should not minus one from this unsigned value and then use it to bound index.

CRAS: linear_resampler - increase resample precision When doing SRC, the actual rate is trimmed to the floor integer before use and causing a precision lost. Multiply the numerator and denominator of the rate factor by 100, so it takes more than 1 day for the lost frames count to be accumulated to 1024.
