[PATCH] Fix missing parens in set_personality()

[Russell King <rmk+lkml@arm.linux.org.uk>]

If you call set_personality() with an expression such as:

	set_personality(foo ? PERS_FOO1 : PERS_FOO2);

then this evaluates to:

	((current->personality == foo ? PERS_FOO1 : PERS_FOO2) ? ...

which is obviously not the intended result.  Add the missing parents
to ensure this gets evaluated as expected:

	((current->personality == (foo ? PERS_FOO1 : PERS_FOO2)) ? ...
