RFR: 8061467: Bad page size passed to setup_large_pages() on Solaris

[Erik Helin]

Hi all,

this small patch fixes a call to Solaris::setup_large_pages that does 
not check if the `alignment_hint` parameter is a valid page size (the 
only such call left).

Webrev:

Bug:
https://bugs.openjdk.java.net/browse/JDK-8061467

Testing:
- Verified that the fix solves the issue on a Solaris machine that
   supported NUMA.
- JPRT

Thanks,
Erik
