Fuhai Wang 6e3844c591 nsfs: fix netns proc warning 
There are two issues in commit a0210fd669343660fc7481f2f422439dba19336c(auth_gss fix:
rpcsec_gss_exit_net has no chance to run when use-gss-proxy==1):
1. there is no chance to remove use-gss-proxy entry when use-gss-proxy does not write to 1.
2. netns evict function should be called earlier than exit function.

error log:
remove_proc_entry: removing non-empty directory 'net/rpc', leaking at least 'use-gss-proxy'
