MAINTAINERS: remove Manish Chopra from QLogic QL4xxx (now orphan)

We have not seen tags from Manish for the QL4xxx driver in over 5 years,
and there is no mailing list activity since Oct 2023. There has been
no maintainer activity in this subsystem at all.

Since there is no other maintainer for this driver it becomes an Orphan.
