Check for error returns from inflateInit()

Browse Source 
At present, it is sufficient to ensure that an error return
from inflateInit() is not ignored. Most error returns, like
Z_VERSION_ERROR and Z_STREAM_ERROR, indicate programming or
build errors. These errors could, perhaps, be handled with
simple asserts. However, for a Z_MEM_ERROR, we may want to
perform some further error handling in the future.
