a58a6a58f5 bcachefs: Switch darray to kvmalloc() 
We sometimes use darrays for quite large buffers - the btree write
buffer in particular needs large buffers, since it must be sized to hold
all the write buffer keys outstanding in the journal.

73ab9e0386 bcachefs: Factor out darray resize slowpath 
Move the slowpath (actually growing the darray) to an out-of-line
function; also, add some helpers for the upcoming btree write buffer
rewrite.
