avcodec/aacsbr_fixed: Fix multiple runtime error: shift exponent 170 is too large for 32-bit type 'int'

It was broken in 091c9860

Modifying data pointer when skipping samples may make it unaligned.
Workaround for Ticket6349.

This should fix the crash of ticket's testcase and a crash/regression
with avxsynth (reported by Michael Niedermayer).

Also change frame->nb_samples < max to frame->nb_samples <= max.
This improves performance. Benchmark:
./ffmpeg -filter_complex "aevalsrc=0:n=1166,firequalizer=fixed=on" -f null null

Currently it does not work at all.

Some samples have their metadata track time_scale incorrectly set to 0
and the check introduced by a398f054
prevents playback of those samples. Setting the time_scale to 1 fixes
playback.

This avoids producing out of range or clipped samples.
