Merge branch 'wlin/reset_ne120_nlmaps_atm2srf' (PR #7865)

Restrict nlmaps_atm2srf_conserve=.true. to v3HR grid

Previously it was set to true for all configurations that use ne120 grid for atm.
This would affect EAM and EAMxx F-cases that use ne120. This change limits its
use to cases that use v3HR grid (ne120pg2 for atm and RRSwISC6to18E3r5 for ocean/ice).
It applies to both coupled and uncoupled configurations.

[BFB] No impact except for cases using ne120 atm grid with other ocean masks
