pkg/cri: optimize slice initialization

Browse Source 
Some of this code was originally added in b7b1200dd3,
which likely meant to initialize the slice with a length to reduce allocations,
however, instead of initializing with a zero-length and a capacity, it
initialized the slice with a fixed length, which was corrected in commit
0c63c42f81.

This patch initializes the slice with a zero-length and expected capacity.
