drm/amd/ras: Remove redundant NULL check in pending bad-bank list iteration

ras_umc_log_pending_bad_bank() walks through a list of pending ECC
bad-bank entries. These entries are saved when a bad-bank error cannot
be processed immediately, for example during a GPU reset.

Later, this function iterates over the pending list and retries logging
each bad-bank error. If logging succeeds, the entry is removed from the
list and the memory for that node is freed.

The loop uses list_for_each_entry_safe(), which already guarantees that
ecc_node points to a valid list entry while the loop body is executing.

Checking "ecc_node &&" inside the loop is therefore unnecessary and
redundant.

Fixes the below:
drivers/gpu/drm/amd/amdgpu/../ras/rascore/ras_umc.c:225 ras_umc_log_pending_bad_bank() warn: variable dereferenced before check 'ecc_node' (see line 223)
