erts: Fix bs_get_integer instruction
The instruction bs_get_integer could unnecessarily trigger a garbage collection
in failure cases which is unwanted or outright dangerous.
Ex:
<<X:Sz,_/bits>> = <<"some binary">>
Previously, if Sz induced X to a bignum it would reserved memory size this on
the heap via a garbage collection before checking if the size could actually match.
It will now check the binary size before triggering a collection.
