i386: hvf: Move Guest LMA reset to macvm_set_cr0()
The only useful purpose of hvf_reset_vcpu() is to clear "IA-32e mode
guest" (LMA) VM-Entry control. But it can be moved to macvm_set_cr0()
which is indirectly used by post-init and post-reset to flush emulator
state. That enables clean removal of hvf_reset_vcpu().
LMA is set only if IA32_EFER.LME = 1, according to Intel SDM "9.8.5
Initializing IA-32e Mode" and "9.8.5.4 Switching Out of IA-32e Mode
Operation", otherwise the entry control can be safely cleared.
