drivers/misc/cs5535-mfgpt.c: fix wrong if condition
Fix the wrong `if' condition for the check if the requested timer is
available.
The bitmap avail is used to store if a timer is used already. test_bit()
is used to check if the requested timer is available. If a bit in the
avail bitmap is set it means that the timer is available.
The runtime effect would be that allocating a specific timer always fails
(versus telling cs5535_mfgpt_alloc_timer to allocate the first available
timer, which works).
