[PATCH] nfsd: Fix error return code in nfsd_file_cache_init()

[Huang Guobin]

Fix to return PTR_ERR() error code from the error handling case instead of
0 in function nfsd_file_cache_init(), as done elsewhere in this function.

Fixes: 65294c1f2c5e7("nfsd: add a new struct file caching facility to nfsd")
