fs: Fix close_on_exec pointer in alloc_fdtable
alloc_fdtable allocates space for the open_fds and close_on_exec bitfields together, as 2 * nr / BITS_PER_BYTE. close_on_exec needs to point to open_fds + nr / BITS_PER_BYTE, not open_fds + nr / BITS_PER_LONG, as introducted in 1fd36adc: Replace the fd_sets in struct fdtable with an array of unsigned longs.
