Naman Jain 404cd6bffe mshv_vtl: Fix vmemmap_shift exceeding MAX_FOLIO_ORDER 
When registering VTL0 memory via MSHV_ADD_VTL0_MEMORY, the kernel
computes pgmap->vmemmap_shift as the number of trailing zeros in the
OR of start_pfn and last_pfn, intending to use the largest compound
page order both endpoints are aligned to.

However, this value is not clamped to MAX_FOLIO_ORDER, so a
sufficiently aligned range (e.g. physical range
[0x800000000000, 0x800080000000), corresponding to start_pfn=0x800000000
with 35 trailing zeros) can produce a shift larger than what
memremap_pages() accepts, triggering a WARN and returning -EINVAL:

  WARNING: ... memremap_pages+0x512/0x650
  requested folio size unsupported

The MAX_FOLIO_ORDER check was added by
commit 646b67d575 ("mm/memremap: reject unreasonable folio/compound
page sizes in memremap_pages()").

Fix this by clamping vmemmap_shift to MAX_FOLIO_ORDER so we always
request the largest order the kernel supports, in those cases, rather
than an out-of-range value.

Also fix the error path to propagate the actual error code from
devm_memremap_pages() instead of hard-coding -EFAULT, which was
masking the real -EINVAL return.

Fixes: 7bfe3b8ea6 ("Drivers: hv: Introduce mshv_vtl driver")
