OvmfPkg/MemEncryptSevLib: clean up MemEncryptSevClearPageEncMask() decl 

The declaration and the definition(s) of the function should have
identical leading comments and/or identical parameter lists. Also remove
any excess space in the comment block, and unindent the trailing "**/" if
necessary. Correct several parameter references.
