[PATCH] fs/ntfs: remove redundant variable idx

[Colin Ian King]

The variable idx is assigned a value and is never read. The variable
is not used and is redundant, remove it.

Cleans up clang scan build warning:
warning: Although the value stored to 'idx' is used in the enclosing
expression, the value is never actually read from 'idx'
