x86/tx_float: save a branch during coefficient deinterleaving 
Directly branch into the special 64-point deinterleave
subroutine rather than going through the general deinterleave.

64-point transform timings on Zen 3:
Before:
   1974 decicycles in           av_tx (fft),16776864 runs,    352 skips
After:
   1956 decicycles in           av_tx (fft),16775378 runs,   1838 skips
