megaraid_sas: Do not use PAGE_SIZE for max_sectors

commit 357ae967ad66e357f78b5cfb5ab6ca07fb4a7758 upstream.

Do not use PAGE_SIZE marco to calculate max_sectors per I/O
request. Driver code assumes PAGE_SIZE will be always 4096 which can
lead to wrongly calculated value if PAGE_SIZE is not 4096. This issue
was reported in Ubuntu Bugzilla Bug #1475166.
