upsampling_{neon,sse41}: fix int sanitizer warning
fixes warnings of the form:
/src/dsp/upsampling_sse41.c:170:1: runtime error: implicit conversion
from type 'int' of value -16 (32-bit, signed) to type 'uintptr_t' (aka
'unsigned long') changed the value to 18446744073709551600 (64-bit,
unsigned)
this is the same change as was done previously in upsampling_sse2.c:
2ee786c7 upsampling_sse2.c: clear int sanitizer warnings
