[PATCH] tpm: Remove dead NULL check in tpm2_flush_space()

The 'space' pointer in tpm2_flush_space() is assigned from
&chip->work_space, which is the address of an embedded struct member
within struct tpm_chip. This address can never be NULL, making the
NULL check dead code. The new code follows the existing pattern
established by the other callers in tpm2-space.c which also assign
from &chip->work_space without a NULL check. Remove the dead code
to avoid confusion.
