hw/i386/kvmvapic: Remove dead code in patch_hypercalls()

Browse Source 
The patch_hypercalls() function sets up a 'patches'
variable and checks it at the end of the function, but
never modifies it in the middle. Remove this dead code,
which seems to have been present since the function was
added in commit e5ad936b0f in 2012.

(Spotted by Coverity: CID 1005581.)
