[PATCH] mshv: Replace fixed memory deposit with status driven helper

[Stanislav Kinsburskii]

Replace hardcoded HV_MAP_GPA_DEPOSIT_PAGES usage with
hv_deposit_memory() which derives the deposit size from
the hypercall status, and remove the now-unused constant.

The previous code always deposited a fixed 256 pages on
insufficient memory, ignoring the actual demand reported
by the hypervisor. hv_deposit_memory() handles different
deposit statuses, aligning map-GPA retries with the rest
of the codebase.

This approach may require more allocation and deposit
hypercall iterations, but avoids over-depositing large
fixed chunks when fewer pages would suffice. Until any
performance impact is measured, the more frugal and
consistent behavior is preferred.
