nvmap: Explicitly import fs symbol for ACK

Browse Source 
Android Common Kernel (ACK) places restrictions on the use of symbols
like close_fd, kernel_write, filp_open, etc, exported by the fs
subsystem. These symbols have to be explicitly imported using
MODULE_IMPORT_NS to avoid build errors. Eventually, synbol usage needs
to be deprecated.
