media: radio: wl1273: fix interrupt masking on release

Browse source 
commit 1091eb830627625dcf79958d99353c2391f41708 upstream.

If a process is interrupted while accessing the radio device and the
core lock is contended, release() could return early and fail to update
the interrupt mask.

Note that the return value of the v4l2 release file operation is
ignored.
