xen/grants: Remove gnttab_max_grant_frames dependency on gnttab_init.

The function gnttab_max_grant_frames() returns the maximum amount
of frames (pages) of grants we can have. Unfortunatly it was
dependent on gnttab_init() having been run before to initialize
the boot max value (boot_max_nr_grant_frames).

This meant that users of gnttab_max_grant_frames would always
get a zero value if they called before gnttab_init() - such as
'platform_pci_init' (drivers/xen/platform-pci.c).
