[PATCH] kernel/freezer.c : Removing extra checking.

["Rakib Mullick" <rakib.mullick@gmail.com>]

Impact: Reduces an extra checking.

Following patch removes an extra checking. We can remove it since, the
current task is frozen. If the current task is not frozen, then it
will return from __else__ condition of freezing(current) check. So,
the check becames unnecessary. It also reduces 32 bytes of text space
on my x86  (32 bit) system.
