[PATCH AUTOSEL 5.16 17/30] HID: amd_sfh: Handle amd_sfh work buffer in PM ops

From: Basavaraj Natikar <Basavaraj.Natikar@amd.com>

[ Upstream commit 0cf74235f4403b760a37f77271d2ca3424001ff9 ]

Since in the current amd_sfh design the sensor data is periodically
obtained in the form of poll data, during the suspend/resume cycle,
scheduling a delayed work adds no value.

So, cancel the work and restart back during the suspend/resume cycle
respectively.
