[Qemu-devel] [PULL for-2.4 2/2] ahci: fix ICC mask definition

[John Snow <jsnow@redhat.com>]

There are likely others that could be updated, but we'll
go with a light touch for 2.4 for now.

Without the Unsigned specifier, this shifts bits into the
signed bit, which makes clang unhappy and could cause
unwanted behavior.
