[ Upstream commit a54e4639c4ef37a0241bac7d2a77f2e6ffb57099 ]

There is a small typo in phm_wait_on_indirect_register().

Swap mask and value arguments provided to phm_wait_on_register() so that
they satisfy the function signature and actual usage scheme.

Found by Linux Verification Center (linuxtesting.org) with Svace static
analysis tool.

In practice this doesn't fix any issues because the only place this
function is used uses the same value for the value and mask.
