I see that the buffer allocated is 22050 bytes (and not 22052 bytes). Yes the hardware supports buffers which are not multiple of period size.

But there may be a (driver) bug that affects the last byte. Try calling

snd_pcm_hw_constraint_integer(runtime, SNDRV_PCM_HW_PARAM_PERIODS);

in the open callback.

Can I forcefully set my buffer size to 22052 bytes

Try the --buffer-size and --period-size parameters of arecord.
