vc/siemens/hwilib: Change uint32_t return type to size_t

Browse Source 
The commit fcff39f0ea ("vc/siemens/hwilib: Rename 'maxlen' to
'dstsize'") changed the 'dstsize' input parameter type from uint32_t to
size_t.

This patch changes also the return parameter, which is often directly
compared with the aforementioned input parameter value. This should
introduce no change on 32-bit builds and stay consistent across the
project in the case of 64-bit builds and avoid comparisons of integers
of different width here.

BUG=none
TEST=No changes to hwilib behavior on any of the siemens/mc_apl1 or
siemens/mc_ehl variants.
