uhd: fix timestamp conversion bug on 32-bit architectures 

Type size_t was used in the UHD time_spec_t to integer
conversion, which would overflow at roughly 4 and a half
hours causing the sample buffer to error on timestamp
validity. Builds where size_t takes on 64-bits were not
affected by this bug.
