ARM: Silence first allocation with CONFIG_ARM_MODULE_PLTS=y

Browse Source 
When CONFIG_ARM_MODULE_PLTS is enabled, the first allocation using the
module space fails, because the module is too big, and then the module
allocation is attempted from vmalloc space. Silence the first allocation
failure in that case by setting __GFP_NOWARN.
