misc: nvsciipc: Fix build for Linux v6.12

Browse Source 
In Linux v6.12, commit 88a2f6468d01 ("struct fd: representation change")
removed the 'struct file' pointer from 'struct fd'. This breaks building
the NVSCIIPC driver that tries to directly access the 'file' pointer
from the 'fd' structure. Fix this by using the helper macros 'fd_empty'
and 'fd_file' as necessary to fix the build.
