hv: Enlarge E820_MAX_ENTRIES to 64

Browse Source 
e820_alloc_memory() splits one E820 entry into two entries. With vEPT
enabled, e820_alloc_memory() is called one more. On some platforms, the
e820 entries might exceed 32.

Enlarge E820_MAX_ENTRIES to 64. Please note, it must be less than 128
due to constrain of zeropage. Linux kernel defines it as 128.
