DECI4P System Drive remote filesystem process. SceDeci4pSDrfp registers a virtual filesystem to read files from the host PC at boot time. This virtual filesystem has a minimal implementation: only
vop_open/vop_close/vop_lookup/vop_read/vop_lseek/vop_inactive functions are implemented. Since this filesystem is just for startup, SceDeci4pDrfp later deletes the virtual filesystem before registering the full deci4p_drfp_dev_fs virtual filesystem.
