Fix potential SCA vulnerability in some EC_METHODs

This commit addresses a potential side-channel vulnerability in the
internals of some elliptic curve low level operations.
The side-channel leakage appears to be tiny, so the severity of this
issue is rather low.

The issue was reported by David Schrammel and Samuel Weiser.
