scsi: storvsc: Explicitly set max_segment_size to UINT_MAX

JIRA: https://issues.redhat.com/browse/RHEL-97171 Upstream Status: From upstream Martin Petersen's linux-scsi branch "fixes" git://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi

storvsc uses virt_boundary to define 'segment' and does not define max_segment_size.

Explicitly set max_segment_size to UINT_MAX, otherwise __blk_rq_map_sg() takes default 64K max segment size and splits one virtual segment into two parts, then breaks virt_boundary limit.

Before commit ec84ca40 ("scsi: block: Remove now unused queue limits helpers"), max segment size was set to UINT_MAX in the case where virt_boundary was defined.
