Audio: MFCC: Fix 64 bit build issue

The comp_err() trace in mfcc_init() causes an error:

sof/src/audio/mfcc/mfcc.c: In function 'mfcc_init':
sof/src/include/sof/audio/component.h:160:20:
  error: format '%u' expects argument of type 'unsigned int',
  but argument 4 has type 'size_t' {aka 'long unsigned int'}
  [-Werror=format=]
