hw_breakpoints: Release the bp slot if arch_validate_hwbkpt_settings() fails.
 
On a given architecture, when hardware breakpoint registration fails
due to un-supported access type (read/write/execute), we lose the bp
slot since register_perf_hw_breakpoint() does not release the bp slot
on failure.
Hence, any subsequent hardware breakpoint registration starts failing
with 'no space left on device' error.

This patch introduces error handling in register_perf_hw_breakpoint()
function and releases bp slot on error.

Some notes regarding the cx18 driver for the Conexant CX23418 MPEG
encoder chip:

1) Currently supported are:

	- Hauppauge HVR-1600
	- Compro VideoMate H900
	- Yuan MPC718
	- Conexant Raptor PAL/SECAM devkit

2) Some people have problems getting the i2c bus to work.
   The symptom is that the eeprom cannot be read and the card is
   unusable. This is probably fixed, but if you have problems
   then post to the video4linux or ivtv-users mailing list.

3) VBI (raw or sliced) has not yet been implemented.

4) MPEG indexing is not yet implemented.

5) The driver is still a bit rough around the edges, this should
   improve over time.


Firmware:
