If the caller has set __GFP_NOWARN don't print the following message:
vmap allocation for size 15736832 failed: use vmalloc=<size> to increase
size.

This can happen with the ARM/Linux or ARM64/Linux module loader built
with CONFIG_ARM{,64}_MODULE_PLTS=y which does a first attempt at loading
a large module from module space, then falls back to vmalloc space.
